عَنْ وَرَّادٍ كَاتِبِ الْمُغِيرَةِ بْنِ شُعْبَةَ أَنَّ الْمُغِيرَةَ رَضِيَ اللَّهُ عَنْهُ كَتَبَ إِلَى مُعَاوِيَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ إِذَا سَلَّمَ قَالَ: ((لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، اللَّهُمَّ لَا مَانِعَ لِمَا أَعْطَيْتَ وَلَا مُعْطِي لِمَا مَنَعْتَ وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ))
It is narrated from the scribe of Sayyiduna Mughirah bin Shu’bah (may Allah be pleased with him), Warrad, that Sayyiduna Mughirah (may Allah be pleased with him) wrote to Sayyiduna Mu’awiyah (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) would finish the prayer with salam, he used to say: "There is no god but Allah, He is alone, He has no partner, to Him belongs the dominion and to Him belongs all praise, and He is over all things Powerful. O Allah! None can withhold what You give, and none can give what You withhold, and the wealth of the wealthy cannot benefit them against You."
