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. (Using translation from Muslim 384)
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «إِذَا سَمِعْتُمُ الْمُؤَذِّنَ فَقُولُوا مِثْلَ مَا يَقُولُ وَصَلَّوْا عَلَيَّ فَإِنَّهُ مَنْ صَلَّى عَلَيَّ صَلَّى الله عَلَيْهِ عَشْرًا ثُمَّ سَلُوا لِيَ الْوَسِيلَةَ فَإِنَّهَا مَنْزِلَةٌ فِي الْجَنَّةِ لَا تَنْبَغِي إِلَّا لِعَبْدٍ مِنْ عِبَادِ اللهِ وَأَرْجُو أَنْ أَكُونَ أَنَا هُوَ فَمَنْ سَأَلَ لِيَ الْوَسِيلَةَ حَلَّتْ عَلَيْهِ الشَّفَاعَةُ»
