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 (ﷺ) say.' So he wrote to him, 'The Prophet of Allah (ﷺ) 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).'"
