Allah the Exalted said:
٢٤٣ - باب الأمر بالصلاة عليه وفضلها وبعض صيغها
Allah the Exalted said:
Indeed, Allāh confers blessing upon the Prophet, and His angels [ask Him to do so]. O you who have believed, ask [Allāh to confer] blessing upon him and ask [Allāh to grant him] peace.
On the authority of ʿAbd Allah ibn ʿAmr ibn al-ʿĀṣ (may Allah be pleased with them both): that he heard the Messenger of Allah ﷺ say: “Whoever invokes one blessing upon me, Allah will send ten blessings upon him for it.” Narrated by Muslim.

On the authority of Aws ibn Aws (may Allah be pleased with him), who said: The Messenger of Allah ﷺ said: “Among the most excellent of your days is Friday, so invoke many blessings upon me on it, for your blessings are presented to me.” They said: “O Messenger of Allah, how can our blessings be presented to you when you have decayed?” — he said: meaning, when you have crumbled to dust. He said: “Indeed Allah has forbidden the earth to consume the bodies of the prophets.” Narrated by Abū Dāwūd with a sound chain.
On the authority of Abū Hurayrah (may Allah be pleased with him), who said: The Messenger of Allah ﷺ said: “May the nose be rubbed in dust of a man before whom I am mentioned and he does not invoke blessings upon me.” Narrated by al-Tirmidhī, who said: “A good (ḥasan) hadith.”

On the authority of ʿAlī (may Allah be pleased with him), who said: The Messenger of Allah ﷺ said: “The miser is the one before whom I am mentioned and he does not invoke blessings upon me.” Narrated by al-Tirmidhī, who said: “A good and sound (ḥasan ṣaḥīḥ) hadith.”
On the authority of Faḍālah ibn ʿUbayd (may Allah be pleased with him), who said: The Messenger of Allah ﷺ heard a man making supplication in his prayer without glorifying Allah the Exalted and without invoking blessings upon the Prophet ﷺ. So the Messenger of Allah ﷺ said: “This man has been hasty.” Then he called him and said to him — or to another: “When one of you prays, let him begin by praising his Lord, glory be to Him, and extolling Him; then let him invoke blessings upon the Prophet ﷺ; then let him supplicate afterwards for whatever he wishes.” Narrated by Abū Dāwūd and al-Tirmidhī, who said: “A good and sound (ḥasan ṣaḥīḥ) hadith.”
On the authority of Abū Muḥammad Kaʿb ibn ʿUjrah (may Allah be pleased with him), who said: The Prophet ﷺ came out to us and we said: “O Messenger of Allah, we already know how to send salutations of peace upon you, so how shall we invoke blessings upon you?” He said: “Say: O Allah, send blessings upon Muḥammad and upon the family of Muḥammad, as You sent blessings upon the family of Ibrāhīm; indeed You are Praiseworthy, Glorious. O Allah, bless Muḥammad and the family of Muḥammad, as You blessed the family of Ibrāhīm; indeed You are Praiseworthy, Glorious.” Agreed upon.

Then the Messenger of Allah ﷺ said: “Say: O Allah, send blessings upon Muḥammad and upon the family of Muḥammad, as You sent blessings upon the family of Ibrāhīm; and bless Muḥammad and the family of Muḥammad, as You blessed the family of Ibrāhīm; indeed You are Praiseworthy, Glorious. And the salutation of peace is as you already know.” Narrated by Muslim.
