that the Messenger of Allah ﷺ said: "If you hear the Muadh-dhin then say as he says. Then send Salat upon me, because whoever sends Salat upon me, Allah will send Salat upon him ten times due to it. Then ask Allah that He gives me Al-Wasilah, because it is a place in Paradise which is not for anyone except for a slave from the slaves of Allah, and I hope that I am him. And whoever asks that I have Al-Wasilah, then (my) intercession will be made lawful for him."
أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ إِذَا سَمِعْتُمُ الْمُؤَذِّنَ فَقُولُوا مِثْلَ مَا يَقُولُ الْمُؤَذِّنُ ثُمَّ صَلُّوا عَلَىَّ فَإِنَّهُ مَنْ صَلَّى عَلَىَّ صَلاَةً صَلَّى اللَّهُ عَلَيْهِ بِهَا عَشْرًا ثُمَّ سَلُوا لِيَ الْوَسِيلَةَ فَإِنَّهَا مَنْزِلَةٌ فِي الْجَنَّةِ لاَ تَنْبَغِي إِلاَّ لِعَبْدٍ مِنْ عِبَادِ اللَّهِ وَأَرْجُو أَنْ أَكُونَ أَنَا هُوَ وَمَنْ سَأَلَ لِيَ الْوَسِيلَةَ حَلَّتْ عَلَيْهِ الشَّفَاعَةُ
