(The clerk of Al-Mughira) Muawiya wrote to Al-Mughira 'Write to me what you have heard from Messenger of Allah ﷺ.' So he (Al-Mughira) wrote to him: Allah's Prophet used to say at the end of each prayer: "La ilaha illalla-h wahdahu la sharika lahu, lahul Mulku, wa lahul Hamdu wa hula ala kulli shai'in qadir. 'Allahumma la mani' a lima a'taita, wala mu'tiya lima mana'ta, wala yanfa'u dhuljadd minkal-jadd." He also wrote to him that the Prophet ﷺ used to forbid (1) Qil and Qal (idle useless talk or that you talk too much about others), (2) Asking too many questions (in disputed Religious matters); (3) And wasting one's wealth by extravagance; (4) and to be undutiful to one's mother (5) and to bury the daughters alive (6) and to prevent your favors (benevolence to others (i.e. not to pay the rights of others (7) And asking others for something (except when it is unavoidable).  

كَتَبَ مُعَاوِيَةُ إِلَى الْمُغِيرَةِ اكْتُبْ إِلَىَّ مَا سَمِعْتَ مِنْ رَسُولِ اللَّهِ ﷺ فَكَتَبَ إِلَيْهِ إِنَّ نَبِيَّ اللَّهِ ﷺ كَانَ يَقُولُ فِي دُبُرِ كُلِّ صَلاَةٍ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهْوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ اللَّهُمَّ لاَ مَانِعَ لِمَا أَعْطَيْتَ وَلاَ مُعْطِيَ لِمَا 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  

[Machine] I heard from the Messenger of Allah ﷺ , then Al-Mugheerah invited me. He wrote to him, "I heard the Messenger of Allah ﷺ say that when he finishes his prayer, he says, 'There is no god but Allah, alone, without partner. His is the dominion, and His is the praise, and He is capable of everything. O Allah, there is no one who can withhold what You give, and no one can give what You withhold, and the true benefit is not from the one who appears to be a benefactor. And I heard him forbid backbiting, spreading gossip, excessive questioning, wasting money, maltreatment of daughters, and disobedience to parents, and from injustice and attacking others without a justifiable reason.  

سَمِعْتَ مِنْ رَسُولِ اللهِ ﷺ فَدَعَانِي الْمُغِيرَةُ قَالَ فَكَتَبَ إِلَيْهِ إِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ إِذَا انْصَرَفَ مِنَ الصَّلَاةِ قَالَ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ اللهُمَّ لَا مَانِعَ لِمَا أَعْطَيْتَ وَلَا مُعْطِيَ لِمَا مَنَعْتَ وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ وَسَمِعْتُهُ يَنْهَى عَنْ قِيلَ وَقَالَ وَعَنْ كَثْرَةِ السُّؤَالِ وَإِضَاعَةِ الْمَالِ وَعَنْ وَأْدِ الْبَنَاتِ وَعُقُوقِ الْأُمَّهَاتِ وَمَنْعٍ وَهَاتِ  

Muawiyah wrote to Al-Mughirah bin Shu'bah saying: "Tell me of something that you heard from the Messenger of Allah ﷺ." He said: "When the Messenger of Allah ﷺ finished praying, he would say: La Ilaha Illallah wahdahu la sharika lah, lahul-mulk wa lahul-hamd wa huwa 'ala kulli shay'in qadir. Allahumma la mani' lima a'taita wa la mu'tia lima mana'ta wa la yanfa'u dhal-jaddi minka al-jadd. (There is none worthy of worship except Allah ﷺ alone with no partner or associate. He is the Dominion and to Him be all praise, and He is able to do all things. O Allah, one can withhold what You have given and none can give what You have withheld, and no wealth or fortune can benefit anyone for from You comes all wealth and fortune.)'" (Using translation from Nasāʾī 1341)   

أَنِ اكْتُبْ إِلَيَّ بِشَيْءٍ سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ ﷺ فَكَتَبَ إِلَيْهِ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ حِينَ يَفْرُغُ مِنْ صَلَاتِهِ «لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ اللَّهُمَّ لَا مَانِعَ لَمَّا أَعْطَيْتَ وَلَا مُعْطِيَ لِمَا مَنَعْتَ وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ»  

[Machine] "That you write to me about a hadith that you heard from the Messenger of Allah ﷺ . So he called his servant and asked him to write: 'Indeed, I heard the Messenger of Allah ﷺ forbidding the mistreatment of daughters, disobedience to mothers, withholding things, spreading rumors, excessive questioning, and wasting money.'"  

أَنِ اكْتُبْ إِلَيَّ بِحَدِيثٍ سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ ﷺ فَدَعَا غُلَامَهُ وَرَّادًا فَقَالَ اكْتُبْ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَنْهَى عَنْ وَأْدِ الْبَنَاتِ وَعُقُوقِ الْأُمَّهَاتِ وَعَنْ مَنْعٍ وَهَاتِ وَعَنْ قِيلَ وَقَالَ وَكَثْرَةِ السُّؤَالِ وَإِضَاعَةِ الْمَالِ»
