Sayyiduna Abu Mas’ud Uqbah bin Amr (may Allah be pleased with him) says that a man came and sat in front of the Messenger of Allah (peace and blessings be upon him), while we were also present with him. He said: O Messenger of Allah! We have recognized how to send salam upon you, (now the question is) when we perform salah, what is the method of sending blessings (salat) upon you? May Allah have mercy on you. The Messenger of Allah (peace and blessings be upon him) remained silent in response (and remained silent for so long that we wished that the man had not asked the question). Finally, the Messenger of Allah (peace and blessings be upon him) said: When you send blessings upon me, say like this:

اللّٰہُمَّ صَلِّ عَلٰی مُحَمَّدٍ النَّبِیِّ الْأُمِّیِّ وَعَلیَ آلِ مُحَمَّدٍ کَمَا صَلَّیْتَ عَلٰی إِبْرَاھِیْمَ وَآلِ إِبْرَاھِیْمَ وَبَارِکْ عَلٰی مُحَمَّدٍ النَّبِیِّ الْأُمِّیِّکَمَا بَارَکْتَ عَلٰی إِبْرَاھِیْمَ وَعَلٰی آلِ إِبْرَاہِیْمَ إِنَّکَ حَمِیْدٌ مَجِیْدٌ۔

Translation: O Allah! Send mercy upon Muhammad, the unlettered Prophet, and upon the family of Muhammad, as You sent mercy upon Ibrahim and the family of Ibrahim. And send blessings upon Muhammad, the unlettered Prophet, as You sent blessings upon Ibrahim and the family of Ibrahim. Surely, You are Praiseworthy, Glorious.
