Qur'an 33:56

إِنَّ ٱللَّهَ وَمَلَـٰٓئِكَتَهُۥ يُصَلُّونَ عَلَى ٱلنَّبِىِّ ۚ يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ صَلُّوا۟ عَلَيْهِ وَسَلِّمُوا۟ تَسْلِيمًا

“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.”
