What prayer did the Prophet Muhammad (saw) reserve for the intercession of his Ummah on the Day of Resurrection?
 Abu Zubair heard Jabir b. Abdullah reporting it from the Apostle of Allah (may peace be upon him):                      For every apostle was a prayer with which he prayed (to his Lord) for his Ummah, but I have reserved my prayer for the intercession of my Ummah on the Day of Resurrection.
