Peace be upon him-. The Qur'an continued to descend upon the Prophet (peace and blessings of Allaah be upon him) continuously until his death. (Peace be upon him) on Islam and the message, every verse or section of the Holy Quran was dealing with a situation in the life of the Prophet (peace and blessings of Allaah be upon him), or solving the problem of what he faced, as we know that the message of Islam, So difficult that human beings can not tolerate them at all, and since the Apostle is praying May Allah be pleased with him - is mortal in the end, it was not able to bear the hardships and pain that faced if the Koran did not descend on him.
