Al-Adab Al-Mufrad, Book 25, Hadith 19 (In-Book) ⓘ

Warrad, the scribe of al-Mughira ibn Shu'ba, said, "Mu'awiya wrote to al-Mughira, saying, 'Write down for me what you heard the Messenger of Allah, may Allah bless him and grant him peace, say.' So he wrote to him, 'The Prophet of Allah, may Allah bless him and grant him peace, used to say at the end of every prayer, "There is no god but Allah alone with no partner. His is the Kingdom and His is the praise and He has power over everything. O Allah, none can withhold what You give nor can anyone give what You withhold. Nor will the wealth of someone with wealth help him against You.' He also write to him, 'He forbade gossip, asking too many questions, and wasting money. He forbade disobeying mothers, burying daughters alive, and he forbade asking people (without real need).'"

حَدَّثَنَا مُوسَى، قَالَ‏:‏ حَدَّثَنَا أَبُو عَوَانَةَ، قَالَ‏:‏ حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عُمَيْرٍ، عَنْ وَرَّادٍ كَاتِبِ الْمُغِيرَةِ قَالَ‏:‏ كَتَبَ مُعَاوِيَةُ إِلَى الْمُغِيرَةِ‏:‏ اكْتُبْ إِلَيَّ مَا سَمِعْتَ مِنْ رَسُولِ اللهِ صلى الله عليه وسلم، فَكَتَبَ إِلَيْهِ‏:‏ إِنَّ نَبِيَّ اللهِ صلى الله عليه وسلم كَانَ يَقُولُ فِي دُبُرِ كُلِّ صَلاَةٍ‏:‏ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، اللَّهُمَّ لاَ مَانِعَ لِمَا أَعْطَيْتَ، وَلاَ مُعْطِيَ لَمَا مَنَعْتَ، وَلاَ يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ، وَكَتَبَ إِلَيْهِ‏:‏ إِنَّهُ كَانَ يَنْهَى عَنْ قِيلَ وَقَالَ، وَكَثْرَةِ السُّؤَالِ، وَإِضَاعَةِ الْمَالِ‏.‏ وَكَانَ يَنْهَى عَنْ عُقُوقِ الأُمَّهَاتِ، وَوَأْدِ الْبَنَاتِ، وَمَنْعٍ وَهَاتِ‏.‏
