إِنَّ اللَّهَ وَمَلائِكَتَهُ يُصَلّونَ عَلَى النَّبِيِّ ۚ يا أَيُّهَا الَّذينَ آمَنوا صَلّوا عَلَيهِ وَسَلِّموا تَسليمًا

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.
