Mukhtasar Muslim

Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: Every prophet has a supplication which is certainly accepted, and every prophet hastened to make that supplication (in this world), but I have kept my supplication hidden for the Day of Resurrection, for the intercession of my ummah. And by Allah’s permission, my intercession will be for every member of my ummah who dies without associating anything with Allah.
