What was the prayer reserved by the Messenger of Allah (peace be upon him) for the intercession of his Ummah on the Day of Resurrection?
 Abu Huraira said:                      The Messenger of Allah (may peace be upon him) said: Every Messenger is endowed with a prayer which is granted and by which he would (pray to his Lord) and it would he granted for him. I have, however, reserved my prayer for the intercession of my Ummab on the Day of Resurrection.
