Muawiya wrote to Mughira, "Write to me what you heard from the Messenger of Allah ﷺ."So Mughira wrote back to him, "The Prophet of Allah ﷺ used to say after every prayer, 'There is no god but Allah alone, with no partner. To Him belongs the dominion, and to Him belongs all praise, and He is capable of all things. O Allah, none can withhold what You give, and none can give what You withhold, and no possessor of fortune benefits from his fortune against You.'"He also wrote to him that the Prophet used to forbid idle talk and gossip, asking too many questions, and wasting wealth, and he used to forbid disobedience to mothers, burying daughters alive, and withholding what is due while demanding what is not.
كتب معاوية إلى المغيرة: اكتب إلي ما سمعت من رسول الله ﷺ، فكتب إليه: إن نبي الله ﷺ كان يقول في دبر كل صلاة: لا إله إلا الله 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 وكتب إليه إنه كان ينهى عن قيل وقال، وكثرة السؤال، وإضاعة المال، وكان ينهى عن عقوق الأمهات، ووأد البنات، ومنع وهات.
