Abdur Rahman bin Abi Laila narrated that once I met Ka'b bin Ujrah (may Allah be pleased with him), and he said, "Shall I not give you a gift (of a hadith) which I heard from the Messenger of Allah (peace and blessings be upon him)?" I said, "Yes, please bestow this gift upon me." He narrated, "We asked the Messenger of Allah (peace and blessings be upon him), 'O Messenger of Allah, how should we send blessings upon you and your family? Allah has already taught us how to send salutations.' The Prophet (peace and blessings be upon him) said, 'Say: O Allah, send Your mercy upon Muhammad and upon the family of Muhammad, as You sent Your mercy upon Ibrahim and upon the family of Ibrahim. Surely, You are Most Praiseworthy, Most Glorious. O Allah, send blessings upon Muhammad and upon the family of Muhammad, as You sent blessings upon Ibrahim and upon the family of Ibrahim. Surely, You are Most Praiseworthy, Most Glorious.'"
