Praise be to Allah, the Lord of the worlds [i.e., people]. Peace be upon our Prophet Muhammad, his family, and all his Companions. The title of this book is inspired from the Prophet's saying: "This person has worked little but was rewarded much." He said that when a man from the Ansar (Helpers) came to him, uttered the testimony of the faith (La Ilaha Illa Allah i.e., No god but Allah), then advanced to the battle to fight until he was killed as reported by Imam Muslim in the chapter on confirming the entrance of a martyr to Paradise. These are selections from authentic Hadiths with short commentaries which I extracted from the books of Hadith explanations. The methodology of selection is the Hadiths which contain great reward for little and easy work, unlike the Hadiths of expiating sins and faults that were written in other books. A reader shall wonder at the mentioned Hadiths because of their great reward for little actions or Adhkar (invocations and Remembrances said at certain times on a regular basis) which a person does or says. However, Allah's Mercy is broad, for He is the Most Generous, the Most Merciful who grants favors more than His Servants think. He (Glory be to Him) exhorts us to Paradise and guides us to the shortest way to it.
