اَللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا صَلَّيْتَ عَلَى إِبْرَاهِيمَ وَعَلَى آلِ إِبْرَاهِيمَ، إِنَّكَ حَمِيدٌ مَجِيدٌ، اَللَّهُمَّ بَارِكَ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا بَارَكْتَ عَلَى إِبْرَاهِيمَ وَعَلَى آلِ إِبْرَاهِيمَ، إِنَّكَ حَمِيدٌ مَجِيدٌ

Allaahumma salli 'alaa Mu'hammadin wa 'alaa 'aali Mu'hammadin, kamaa sallayta 'alaa 'Ibraaheema wa 'alaa 'aali 'Ibraaheema, 'innaka Hameedun Majeed. Allaahumma baarik 'alaa Mu'hammadin wa 'alaa 'aali Mu'hammadin, kamaa baarakta 'alaa 'Ibraaheema wa 'alaa 'aali 'Ibraaheema, 'innaka Hameedun Majeed

O Allah, bestow Your favor on Muhammad (ﷺ) and on the family of Muhammad (ﷺ) as You have bestowed Your favor on Ibrahim (Ah) and on the family of Ibrahim (Ah), You are Praiseworthy, Most Glorious. O Allah, bless Muhammad (ﷺ) and the family of Muhammad (ﷺ) as You have blessed Ibrahim and the family of Ibrahim (Ah), You are Praiseworthy, Most Glorious. Abdullah bin Amr bin al-As (RA) reported Allah's Messenger (ﷺ) as saying: When you hear the Mu'adhdhin, repeat what he says, then invoke a blessing on me, for everyone who invokes a blessing on me will receive ten blessings from Allah; then beg from Allah al-Wasila for me, which is a rank in Paradise fitting for only one of Allah's servants, and I hope that I may be that one. If anyone who asks that I be given the Wasila, he will be assured of my intercession.
