Protective jealousy is an innate noble characteristic upon which a sound person whom Allah has honored and favored was created. Islam elevated the rank of this sublime trait and laudably mentioned it to the extent that it considers defending one's honor and being protectively jealous about inviolable matters a type of Jihaad. For this, a person may offer everything and sacrifice his soul, and such a person would be at the same rank as the martyr in Paradise. It was narrated on the authority of Sa‘eed ibn Zayd, may Allah be pleased with him, that he said, “I heard the Prophet 
saying: ‘A person who is killed while protecting his property is a martyr, a person who is killed while defending his life is a martyr, a person who is killed while defending his religion is a martyr, and a person who is killed while defending his family is a martyr.’

The Meaning of Protective Jealousy
It is a change in the state of the heart and feelings of anger that arise due to a person's feeling that others might share or aspire to share something that he owns. This feeling appears among the spouses. Both men and women share this instinct, although the protective jealousy of women is greater. This feeling becomes more intense when the woman feels that her husband is betraying her or that he desires another woman. Likewise, the man feels the same when he has suspicions regarding his wife's behavior or feels that she desires other men.
Protective Jealously from the Sharee'ah Viewpoint
For both men and women, protective jealousy, when called for and shown in a moderate way, is a praiseworthy trait and it is a necessity for spouses in order that they can live in kindness. Each of them also has to consider the protective jealousy of the other and know that every matter has a moderate and sensible point between its two extremes. It was proven that the Prophet said: “There is jealousy that Allah loves and jealousy that He hates. There is pride that Allah loves and pride that He hates. The jealousy that Allah loves is jealousy regarding a matter of suspicion. The jealousy that He hates is jealousy regarding something that is not doubtful. The pride that Allah loves is a man's pride when fighting and when giving in charity. The pride that Allah hates is that shown in oppression and boasting.” [Ahmad and others, Al-Albaani - Saheeh]
Protective Jealousy is an Indication of Manliness
Protective jealousy, when justified and shown in a moderate manner, is an indication of true manhood. It leads to the protection of honor, the safeguarding of sacred ordinances, the veneration of the symbols of Allah, and the promotion of adherence to the limits that He has set. It denotes the strength of one's faith and shows that it is instilled in his heart. Little wonder then that unethical practices, impermissible exposure of women's beauty, immorality and licentiousness prevails throughout the western world and other similar communities. The reason behind this is either the lack of or the complete absence of protective jealousy.
Even in the pre-Islamic era, this characteristic prevailed among the Arabs who experienced the meanings of these virtues. They would be protectively jealous even about their neighbors' honor from their own desires. Manly zeal could also drive these people to incite wars for the sake of any assault against a woman, to protect her honor, or in response to her seeking refuge. The cause of the war of Al-Fijaar that broke out between the Arabs was that a group of youth from Banu Kinaanah saw a woman in the market of ‘Ukaath and asked her to uncover her face, and when she refused they began mocking her. Thereupon, she screamed, “O people of ‘Aamir!” Immediately their fighters responded to her request. The tribe of Kinaanah stood to defend their youth. The tribe of Hawaazin stood on the side of Banu ‘Aamir and Quraysh stood on the side of Kinaanah, which resulted in a countless number of victims and much bloodshed.
Excessive Protective Jealousy
Excessive jealousy is a source of trouble for the person and those around him. Many so-called honor-related crimes are committed due to rumors. This extent of jealousy, which is hazardous, may drive a person to kill others without any justification or sound evidence for his action. This happens in many places. Some husbands have the disease of bitter doubts which turns their marital life into unbearable turmoil. It was narrated that the Prophet forbade that a man should unexpectedly come to his wife at night, doubting her fidelity and probing into her lapses. [Muslim] It is improper for a husband to have no confidence in his wife, and he should not be excessive in monitoring her each and every action. There is no doubt that such behavior damages the marital relationship and severs what Allah The Almighty has ordered to be joined.
‘Ali ibn Abi Taalib, may Allah be pleased with him, would say, “Do not have excessive jealousy over your wives such that you would cause them to be slandered.” Also, Mu‘aawiyah, may Allah be pleased with him, said, “There are three characteristics of nobility: Forgiveness, having a flat abdomen and avoiding excessive protective jealousy.”
Therefore, moderation in this regard is very important and the limits of the required protective jealousy are determined by the texts of the Sharee'ah. It was narrated that the Prophet said: “Allah becomes jealous and the believer also becomes jealous. Allah becomes jealous when the believer commits what He has forbidden.” [Al-Bukhari]
Protective jealousy is required if women violate the prohibitions of Allah The Almighty, and in this case such jealousy is praiseworthy. Conversely, being void of such jealousy in these situations is dispraised and is the cause of a person being prevented from entering Paradise. The proof of this is what was narrated on the authority of ‘Ammaar ibn Yaasir, may Allah be pleased with him, that the Prophet said: “There are three types of people who will never enter Paradise: A Dayyooth, a woman who assumes a masculine attitude and an alcoholic.” His Companions asked, “O Messenger of Allah, we know what an alcoholic is, but what is a Dayyooth?” He replied: “He is the person who does not care who has private access to his womenfolk.” The Companions asked, “Who are the women who assume a masculine attitude?” He replied: “They are women who imitate men.”
Considering the Protective Jealousy of Others
When a man feels the pain of a loss or jealousy when his friend forsakes him and befriends someone else, then we should consider the jealousy of the mother-in-law. A mother in this situation feels as if she has lost her son to someone else, after having cared for him throughout his entire life and sacrificed every dear and precious thing to make him a man of consequence in this life. Also, just as the person feels jealous over his wife, he should consider her jealousy over him. It is improper to show his admiration for other women, not to mention narrating his pre or post-marital relationships, as this is not a source of pride. Rather, a person should keep it hidden, repent from such an act if they have happened, and adhere to Sitr (covering and protection).
A woman should also control herself as much as she can, otherwise her jealousy would be irrepressible. Commenting on the verse in which Allah The Almighty Says (what means): {And they will have therein purified spouses.} [Quran 2:25], Ibn Al-Qayyim 
said, “They are purified from menstruation, urination and any harm that afflicts women in this world. Their souls are also purified from jealousy, wanting to harm their husbands and desire for other men.”
The Jealousy of Allah The Exalted
Sharee'ah texts prove that Allah The Exalted becomes jealous . His jealousy is a fact and He becomes jealous in a manner that befits His majesty and perfection. A manifestation of His Jealousy is His dislike that His slave should fall into acts of disobedience or associate anything in what is due solely to Him in terms of obeying His commands and avoiding His prohibitions. It was narrated that the Prophet said: “Allah becomes jealous and the believer also becomes jealous. Allah becomes jealous when the believer commits what He has forbidden.” [Al-Bukhari] In another Hadeeth, he said: “No one is more jealous than Allah The Almighty. Because of His jealousy, Allah has prohibited immorality, both apparent and concealed, and no one likes to be praised more than Allah The Almighty.” [Al-Bukhari and Muslim] Another narration of this Hadeeth states: “The believer gets jealous and Allah is even more jealous.” [Al-Bukhari and Muslim]
It was narrated in a Hadeeth that the Prophet said to his Companions, may Allah be pleased with them, about one of them: “Are you surprised at Sa‘d's jealousy over his honor? By Allah, I am more jealous over my honor than he is over his, and Allah is more jealous than I am.” [Al-Bukhari and Muslim]
The Protective Jealousy of the Husband over his Wife
As stated previously, it was narrated that Sa‘d ibn ‘Ubaadah, may Allah be pleased with him, said, “If I were to see a man with my wife, I would strike him with a sword, and not with the flat side of it.” When the Messenger of Allah heard this, he said: “Are you surprised at Sa‘d's jealousy over his honor? By Allah, I am more jealous over my honor than he is over his, and Allah is more jealous than I am.” [Al-Bukhari and Muslim]
It was narrated that when the rebels entered into the presence of ‘Uthmaan ibn ‘Affaan, may Allah be pleased with him, his wife Naa’ilah, spread her hair out as she was entreating the chivalry of the rebels. Thereupon ‘Uthmaan, may Allah be pleased with him, shouted at her, and said, “Cover yourself! By Allah, death is easier for me than the violation of the sanctity of your hair.” Therefore, the husband's protective jealousy over his wife motivates him to protect and safeguard her from anything that might harm her honor or disrespect her dignity.
The Protective Jealousy of the Wife over her Husband
One day the Prophet asked ‘Aa’ishah, may Allah be pleased with her: “Are you jealous?” She replied in astonishment, “And how could someone like me not become jealous over someone like you?” [Muslim] It was narrated on the authority of Anas, may Allah be pleased with him, that he said,
While the Prophet was in the house of one of his wives, one of the Mothers of the Believers sent a meal in a dish. The wife at whose house the Prophet was, struck the hand of the servant, causing the dish to fall and break. The Prophet gathered the broken pieces of the dish and then started collecting the food on them which had been in the dish, and said: “Your mother [my wife] felt jealous.” Then he detained the servant until an [unbroken] dish was brought from the wife at whose house he was. He gave the unbroken dish to the wife whose dish had been broken and kept the broken one at the house where it had been broken. [Al-Bukhari]
Incidents that Were Motivated by Manly Zeal
Narrating the events of the 286th Hirji year, Al-Haafith Ibn Katheer quoted what was mentioned in Al-Muntathim,
From the wonders that occurred during that year, a woman sued her husband before the judge of Ar-Rayy [a city in modern day Iran]. She claimed that she had 500 Dinars as her deferred portion of her dowry, but her husband denied this. She managed to get proof to support her plea. She was then told that she had to uncover her face in order to make sure that she was the wife. When this was insisted upon, the husband became jealous and said, “Do not uncover her face. She is truthful in her claim.” He confessed that her claim was true in order to avoid other people seeing his wife's face. When the wife realized what had happened and that he had confessed so that others would not see her face, she said: “I absolve him of the deferred portion of my dowry in this world and in the Hereafter.”
Al-Haafith As-Sam‘aani added in Al-Ansaab, “Having admired their jealousy, the judge said: ‘This incident is to be added to the historical record of noble manners.’”
Some historians mentioned the following incident as one of the good deeds of Al-Hajjaaj ibn Yoosuf Ath-Thaqafi: It was narrated that a Muslim woman was taken captive in India and she pleaded for the help of Al-Hajjaaj, and said, “O Hajjaaj!” When the news reached him, he replied, “At your call!” He spent seven million Dirhams to be able to rescue her.
Then there is the story of a noble Muslim woman who was captured by the Romans. The only relation between her and the Caliph, Al-Mu‘tasim-billaah, was the brotherhood of Islam. When she was tortured by the prince of ‘Amooriyah, she cried for his help and released a shout that was so huge that its echo was recorded in history. She cried, “O Mu‘tasim!” He received the news of her cry while he was resting. He immediately responded, saying, “At your call!” He mobilized a huge army of Muslim soldiers, who set off with him. Each one of them was filled with pride and enthusiasm due to the manly zeal over the honor of this woman. They defeated the enemies and marched closer and closer to their country, breaking into their fortresses until they reached ‘Amooriyah and destroyed its fortresses. They marched until they reached the captured woman and, thereupon, Al-Mu‘tasim said to her, “I ask you to testify before your great grand-father, the Messenger of Allah on the Day of Judgment that I came to rescue you.”
In the seventh century after Hijrah, disunity struck the Muslims such that they became weak. Therefore, the crusaders conquered parts of their countries and aspired for further occupation. They sought the help of one group of Muslims against the other until they almost conquered Egypt. The Fatimide ruler of Egypt during that time, Al-‘Aadhid lideen-illaah, thought to seek the help of the governor of Ash-Shaam, Noor Ad-Deen Zinki, but how could he accept when the king of Ash-Shaam himself did not recognize the caliphate of the Fatimide ruler in Egypt and denied the legitimacy of his governance and rule? He was an affiliate to the caliphate of the Abbasids in Baghdad, who were struggling with the Fatimides. Al-‘Aadhid decided to use manly zeal over Muslim women and their honor in order to solve the problem: He sent a message to Noor Ad-Deen Zinki seeking his aid and accompanied it with the most influential summons: the locks of hair of his womenfolk in the caliphate in Cairo. This had a strong impact on Noor Ad-Deens's heart. It aroused feelings of jealousy and chivalry in the hearts of the soldiers of Ash-Shaam as well as its people. To rescue Egypt from the crusaders, they sacrificed the best of their soldiers under the leadership of Asad Ad-Deen Shirkooh and Yoosuf ibn Ayyoob (Salah Ad-Deen Al-’Ayyoobi). That was the influence that a lock of a woman's hair had, which changed the course of history. This was followed by the battle of Hitteen during which the sacred land (Palestine) was cleansed from disgrace and the crusaders were forced to leave.
While Muslims live by and enjoy these feelings of jealousy and manly zeal in their societies, which elevates their ranks way above the stars and raises them to the most sublime of ranks in virtue and purity, the non-Muslim societies in the East and the West experience the life of weak men (Dayyooths) and procurers, filth and impurities, indecency and disgrace, humiliation and shame. Indeed, some animals would refuse to experience such a life: Some male animals get jealous over their females, and in order to protect her, the male fights others until the strongest one of them finally wins. How truthful our prominent scholars were when they said, “Every nation whose men have weak manly zeal, its women do not properly maintain their chastity.”
