It is narrated from Hazrat Buraidah Khuzai (may Allah be pleased with him) that once we asked in the presence of the Prophet, "O Messenger of Allah! We have come to know how to send salutations (salaam) upon you, now tell us how should we send blessings (durood) upon you?" The Noble Prophet (peace and blessings be upon him) said, "Say like this: O Allah! Send Your favors, mercy, and blessings upon Muhammad (peace be upon him) and his family, as You sent upon the family of Ibrahim (peace be upon him). Surely, You are Praiseworthy and Glorious."
