In-book no 1506حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنِ الْمُسَيَّبِ بْنِ رَافِعٍ، عَنْ وَرَّادٍ، مَوْلَى الْمُغِيرَةِ بْنِ شُعْبَةَ عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، كَتَبَ مُعَاوِيَةُ إِلَى الْمُغِيرَةِ بْنِ شُعْبَةَ أَىُّ شَىْءٍ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقُولُ إِذَا سَلَّمَ مِنَ الصَّلاَةِ فَأَمْلاَهَا الْمُغِيرَةُ عَلَيْهِ وَكَتَبَ إِلَى مُعَاوِيَةَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقُولُ " لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ اللَّهُمَّ لاَ مَانِعَ لِمَا أَعْطَيْتَ وَلاَ مُعْطِيَ لِمَا مَنَعْتَ وَلاَ يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ " .
Al-Mughirah b. Shu'bah reported: "Mu'awiyah wrote to al-Mughirah b. Shu'bah: 'What would the the Messenger of Allah (ﷺ) recite when he gave Taslim (salutation) in the prayer ?' Al-Mughirah dictated and wrote to Mu'awiyah: 'The Messenger of Allah (ﷺ) used to say (at the end of the prayer after taslim): 'There is no God but Allah, Alone, Who has no partner, to Him belongs the dominion, to Him praise is due, and He is Omnipotent. O Allah no one cane withhold what You give and give what You withhold, and none benefits the fortunate person, for from You is the fortune. '"
