سنن النسائي#678Sahihأَخْبَرَنَا سُوَيْدٌ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ حَيْوَةَ بْنِ شُرَيْحٍ، أَنَّ كَعْبَ بْنَ عَلْقَمَةَ، سَمِعَ عَبْدَ الرَّحْمَنِ بْنَ جُبَيْرٍ، مَوْلَى نَافِعِ بْنِ عَمْرٍو الْقُرَشِيِّ يُحَدِّثُ أَنَّهُ سَمِعَ عَبْدَ اللَّهِ بْنَ عَمْرٍو، يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِذَا سَمِعْتُمُ الْمُؤَذِّنَ فَقُولُوا مِثْلَ مَا يَقُولُ وَصَلُّوا عَلَىَّ فَإِنَّهُ مَنْ صَلَّى عَلَىَّ صَلاَةً صَلَّى اللَّهُ عَلَيْهِ عَشْرًا ثُمَّ سَلُوا اللَّهَ لِيَ الْوَسِيلَةَ فَإِنَّهَا مَنْزِلَةٌ فِي الْجَنَّةِ لاَ تَنْبَغِي إِلاَّ لِعَبْدٍ مِنْ عِبَادِ اللَّهِ أَرْجُو أَنْ أَكُونَ أَنَا هُوَ فَمَنْ سَأَلَ لِيَ الْوَسِيلَةَ حَلَّتْ لَهُ الشَّفَاعَةُ " .
Abdullah bin 'Amr said:"I heard the Messenger of Allah (S.A.W) say: 'When you hear the Mu'adhdhin then say what he says, and do Salah upon me, for whoever does Salah upon me once, Allah will Salah upon him ten (times). Then ask Allah to grant me Al-Wasilah, which is a position in paradise which only one of the slaves of Allah will attain, and I hope that I will be the one. Whoever asks for Al-Wasilah for me, will be entitled to my intercession
