1_Because the whole Qur'an addresses the Prophet Muhammad and peace be upon him, and all the verses in the Qur'an  address the Prophet, When I talk to you I do not mention your name so much because I'm talking to you and you hear me, but when I remind you of memories or past or Actual stories it is important to mention names.

2_The Holy Qur'an descended on Muhammad (peace and blessings of Allaah be upon him), so he tells him about the stories of the previous prophets
Therefore we see that Qur'an mentioned the name of Jesus and his mother more than the name of Muhammad, and imagine if the name of the mother of the Prophet peace be upon him or his father, you said that the Qur'an is specific to Muhammad peace be upon him ,,

The Prophet (peace and blessings of Allaah be upon him) mentioned several ways in the Qur'an. Qur'an mentioned his name (Muhammad), mentioned his name (Ahmad) once, and mentioned it as (the Prophet) about thirty times,as well as describing the message (Messenger) perhaps fifty times, This means that the Prophet (peace and blessingsof Allaah be upon him) mentioned in the Qur'an all the descriptions necessary to know the Muslim in terms of the arbitrator, and he has in his hand the definitive argument in about ninety times.
