Muawiya wrote to Mughira, "Write to me something you heard from the Messenger of Allah ﷺ."He replied that whenever he finished his prayer, he would say, "There is no god but Allah." I think he also said, "alone, with no partner. To Him belongs the dominion, to Him belongs all praise, and He is capable of all things. O Allah, none can withhold what You grant, and none can grant what You withhold, and the fortune of the fortunate cannot avail him against You."
حدثنا روح حدثنا ابن عون قال أنبأني أبو سعيد قال
كتب معاوية إلى المغيرة اكتب إلي بشيء سمعته من رسول الله ﷺ فقال كان إذا صلى ففرغ قال لا إله إلا الله قال وأظنه قال وحده لا شريك له له الملك وله الحمد وهو على كل شيء قدير اللهم لا مانع لما أعطيت ولا معطي لما منعت ولا ينفع ذا الجد منك الجد
