Sahih Muslim Book - 5, Hadith - 1338

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ أَخْبَرَنَا جَرِيرٌ عَنْ مَنْصُورٍ عَنِ الْمُسَيَّبِ بْنِ رَافِعٍ عَنْ وَرَّادٍ مَوْلَى الْمُغِيرَةِ بْنِ شُعْبَةَ قَالَ كَتَبَ الْمُغِيرَةُ بْنُ شُعْبَةَ إِلَى مُعَاوِيَةَ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- كَانَ إِذَا فَرَغَ مِنَ الصَّلاَةِ وَسَلَّمَ قَالَ « لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ اللَّهُمَّ لاَ مَانِعَ لِمَا أَعْطَيْتَ وَلاَ مُعْطِىَ لِمَا مَنَعْتَ وَلاَ يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ ».

It was narrated that Warrad, the freed slave of Al-Mughirah bin Shu'bah, said: "Al-Mughirah bin Shu'bah wrote to Mu'awiyah saying that when the Messenger of Allah (s.a.w) had finished his prayer and said the Salam, he said: 'La ilaha ill-Allahu wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu wa huwa 'ala kulli shay'in qadir. Allahumma la mani'a lima a'taita, wa la mu'tiya lima man'at, wa la yanfa'u dhal-jaddi minkal-jadd (There is none worthy of worship but Allah alone, with no partner or associate. His is the Dominion, to Him be praise, and He is Able to do all things. O Allah, none can withhold what You give, and none can give what You withhold, and the good fortune of any fortunate person is of no avail against You.)"'
