Narrated Warrad: (The clerk of Al-Mughira) Muawiya wrote to Al-Mughira 'Write to me what you have heard from Allah's Messenger 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 I Qil and Qal (idle useless talk or that you talk too much about others), II Asking too many questions (in disputed Religious matters); III And wasting one's wealth by extravagance; IV and to be undutiful to one's mother V and to bury the daughters alive VI and to prevent your favors (benevolence to others (ie not to pay the rights of others VII And asking others for something (except when it is unavoidable).
