It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) would be (in the Tashahhud of) two rak'ahs as if he were on a hot stone. I asked: Until he would stand up? He said: Until he would stand up.

(Second chain) They said: It was as if the sitting of the Messenger of Allah, peace and blessings be upon him, in the two rak‘ahs was on a hot stone.

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.

(Second chain) They said: It was asked of you, O Messenger of Allah! How should we send blessings upon you? So the Prophet (peace and blessings be upon him) said: Say like this: O Allah, send blessings upon Muhammad and upon the family of Muhammad, and bless Muhammad and the family of Muhammad, as You blessed Ibrahim in the worlds. Indeed, You are Praiseworthy, Glorious.

(Second chain) It is also narrated from Sayyiduna Uqbah bin Amr (may Allah be pleased with him), who says: The Messenger of Allah (peace and blessings be upon him) came to us in the gathering of Sa’d bin Ubadah. Sayyiduna Bishr bin Sa’d (may Allah be pleased with him) said to him: O Messenger of Allah! Allah has commanded us to send blessings upon you, so how should we send blessings upon you? The Messenger of Allah (peace and blessings be upon him) remained silent until we wished that he had not asked you (peace and blessings be upon him) this question. Then he said: You should say like this:“O Allah, send blessings upon Muhammad and upon the family of Muhammad as You sent blessings upon Ibrahim, and bless Muhammad as You blessed the family of Ibrahim among the worlds; indeed, You are Praiseworthy, Glorious.”And as for Salam, you already know about it.

The companion of the Messenger, Sayyiduna Fadala bin Ubaid (may Allah be pleased with him), says that the Messenger of Allah (peace and blessings be upon him) heard a man supplicating in prayer, while he neither mentioned Allah Almighty nor sent blessings upon you (peace and blessings be upon him), and said: This servant has been hasty. Then you (peace and blessings be upon him) called him and said to him and to others: When any of you prays, he should begin by praising and glorifying Allah Almighty, then send blessings upon the Prophet, then supplicate for whatever he wishes.

It is narrated from Sayyiduna Ka’b bin ‘Ujrah (may Allah be pleased with him) that a man said to the Noble Prophet (peace and blessings be upon him): O Messenger of Allah! We have learned how to send salutations (salam) upon you, now the question is, what is the method of sending blessings (durood)? The Prophet (peace and blessings be upon him) said: Say like this:“O Allah, send blessings upon Muhammad and upon the family of Muhammad as You sent blessings upon Ibrahim; indeed, You are Praiseworthy, Glorious. O Allah, bless Muhammad and the family of Muhammad as You blessed Ibrahim; indeed, You are Praiseworthy, Glorious.”

Ibn Abi Layla says: I met Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him) and he said: Shall I not give you a gift? (And that is) the Messenger of Allah (peace and blessings be upon him) came to us, and we said: O Messenger of Allah! Indeed, we have learned how to send peace upon you, now what is the way to send blessings (salat)? He (peace and blessings be upon him) said: You should say like this: "O Allah, send blessings upon Muhammad and upon the family of Muhammad as You sent blessings upon the family of Ibrahim, indeed You are Praiseworthy, Glorious. O Allah, bless Muhammad and the family of Muhammad as You blessed the family of Ibrahim, indeed You are Praiseworthy, Glorious."

It is narrated from Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him), he says: When this verse {إِنَّ اللَّہَ وَمَلاَئِکَتَہُ یُصَلُّوْنَ عَلَی النَّبِیِّ} was revealed, the people said: O Messenger of Allah! How should we send blessings upon you? The Prophet (peace and blessings be upon him) said: You should say: "O Allah, send blessings upon Muhammad and upon the family of Muhammad, as You sent blessings upon Ibrahim and upon the family of Ibrahim. Indeed, You are Praiseworthy, Glorious. And bless Muhammad and the family of Muhammad, as You blessed Ibrahim and the family of Ibrahim. Indeed, You are Praiseworthy, Glorious." He says: While reciting this salutation, we would also say these words: "And upon us along with them." Yazid, the narrator, says: I could not understand whether these last words were added by Ibn Abi Layla himself or if Sayyiduna Ka'b had actually narrated them.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) says that we said: O Messenger of Allah! We know how to send peace (salam) upon you, now what is the way to send blessings (salat) upon you? The Prophet (peace and blessings be upon him) said: You should say like this: O Allah, send blessings upon Muhammad, Your servant and Messenger, as You sent blessings upon Ibrahim. And send blessings upon Muhammad and the family of Muhammad as You sent blessings upon Ibrahim and the family of Ibrahim.
