Sura 33 Al-Ahzab (Those who took up arms), ayat 56

1. إِنَّ اللَّهَ وَمَلَائِكَتَهُ يُصَلُّونَ عَلَى النَّبِيِّ ۚ يَا أَيُّهَا الَّذِينَ آمَنُوا صَلُّوا عَلَيْهِ وَسَلِّمُوا تَسْلِيمًا

   Indeed, Allah confers blessing upon the Prophet, and His angels (ask Him to do so). O you who have believed, ask (Allah to confer) blessing upon him and ask (Allah to grant him) peace.

   33:56
