Al-Adab Al-Mufrad 298
Warrad, the scribe of al-Mughira ibn Shu'ba, said, "Mu'awiya wrote to al-Mughira ibn Shu'ba, saying, 'Write down for me something which you heard the Messenger of Allah, may Allah bless him and grant him peace.' Al-Mughira wrote to him, ' The Messenger of Allah ﷺ used to forbid gossip, wasting money, asking too many questions, refusing to give, disobedience to parents, and burying daughters alive."
حَدَّثَنَا مُحَمَّدُ بْنُ سَلامٍ، قَالَ: حَدَّثَنَا هُشَيْمٌ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، قَالَ: حَدَّثَنَا وَرَّادٌ كَاتِبُ الْمُغِيرَةِ قَالَ: كَتَبَ مُعَاوِيَةُ إِلَى الْمُغِيرَةِ بْنِ شُعْبَةَ: أَنِ اكْتُبْ إِلَيَّ بِشَيْءٍ سَمِعْتَهُ مِنْ رَسُولِ اللهِ ﷺ، فَكَتَبَ إِلَيْهِ الْمُغِيرَةُ: أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَنْهَى عَنْ قِيلَ وَقَالَ، وَإِضَاعَةِ الْمَالِ، وَكَثْرَةِ السُّؤَالِ، وَعَنْ مَنْعٍ وَهَاتِ، وَعُقُوقِ الأُمَّهَاتِ، وَعَنْ وَأْدِ الْبَنَاتِ.
