abudawud:4920[Chain 1] Naṣr b. ʿAlī > Sufyān > al-Zuhrī [Chain 2] Musaddad > Ismāʿīl [Chain 3] Aḥmad b. Muḥammad b. Shabbūyah al-Marwazī > ʿAbd al-Razzāq > Maʿmar > al-Zuhrī > Ḥumayd b. ʿAbd al-Raḥman from his mother

The Prophet ﷺ said: He who forged in order to put things right between two persons did not lie. The version by Ahmad ibn Muhammad and Musaddad has: The liar is not the one who puts things right between people, saying what is good and increasing good.  

أبو داود:٤٩٢٠حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ أَخْبَرَنَا سُفْيَانُ عَنِ الزُّهْرِيِّ ح وَحَدَّثَنَا مُسَدَّدٌ حَدَّثَنَا إِسْمَاعِيلُ ح وَحَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدِ بْنِ شَبُّويَةَ الْمَرْوَزِيُّ حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ عَنِ الزُّهْرِيِّ عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أُمِّهِ

أَنَّ النَّبِيَّ ﷺ قَالَ لَمْ يَكْذِبْ مَنْ نَمَى بَيْنَ اثْنَيْنِ لِيُصْلِحَ وَقَالَ أَحْمَدُ بْنُ مُحَمَّدٍ وَمُسَدَّدٌ لَيْسَ بِالْكَاذِبِ مَنْ أَصْلَحَ بَيْنَ النَّاسِ فَقَالَ خَيْرًا أَوْ نَمَى خَيْرًا
