That ʿAbdullah bin Abi Hadrad Al-Aslami owed him some debt. Kaʿb met him and caught hold of him and they started talking and their voices grew loudest. The Prophet ﷺ passed by them and addressed Kaʿb, pointing out to him to reduce the debt to one half. So, Kaʿb got one half of the debt and exempted the debtor from the other half. (Using translation from Bukhārī 2424)   

أَنَّهُ كَانَ لَهُ مَالٌ عَلَى عَبْدِ اللهِ بْنِ أَبِي حَدْرَدٍ الْأَسْلَمِيِّ فَلَقِيَهُ فَلَزِمَهُ فَتَكَلَّمَا حَتَّى ارْتَفَعَتِ الْأَصْوَاتُ فَمَرَّ بِهِمَا رَسُولُ اللهِ ﷺ فَقَالَ يَا كَعْبُ وَأَشَارَ بِيَدِهِ كَأَنَّهُ يَقُولُ النِّصْفَ فَأَخَذَ نِصْفَ مَا عَلَيْهِ وَتَرَكَ نِصْفًا  

I brought my debtor to the Holy Prophet ﷺ. He said to me: Stick to him. He again said to me: O brother of Banu Tamim, what do you want to do with your prisoner. (Using translation from Abū Dāʾūd 3629)   

أَتَيْتُ النَّبِيَّ ﷺ بِغَرِيمٍ لِي فَقَالَ لِي الزَمْهُ ثُمَّ قَالَ لِي يَا أَخَا بَنِي تَمِيمٍ مَا تُرِيدُ أَنْ تَفْعَلَ بِأَسِيرِكَ؟  

[Machine] "That the Messenger of Allah ﷺ prepared for his enemy and said, 'Stay with him.' Then he met him after that and said, "What did your captive (prisoner) do, O brother of Bani Al-Anbar?"  

أَنَّهُ اسْتَعْدَى رَسُولَ اللهِ ﷺ عَلَى غَرِيمِهِ فَقَالَ الزَمْهُ ثُمَّ لَقِيَهُ بَعْدَ ذَلِكَ فَقَالَ مَا فَعَلَ أَسِيرُكَ يَا أَخَا بَنِي الْعَنْبَرِ؟  

[Machine] Until now, O father, until now, O father, whoever seeks his brother should seek him with gentleness and kindness, or otherwise. When he heard that, he left him and followed him. He said, "O Prophet of Allah, before you said whoever seeks his brother should seek him with gentleness and kindness, or otherwise. He said, "Yes." He said, "O Prophet of Allah, what is gentleness?" He said, "Not insulting him, not being overly strict with him, not being vulgar towards him, and not harming him." He said, "And what is kindness or otherwise?" He said, "Giving him his due rights or leaving part of it."  

حَتَّى الْآنَ يَا أُبِيُّ حَتَّى الْآنَ يَا أُبِيُّ مَنْ طَلَبَ أَخَاهُ فَلْيَطْلُبْهُ بِعَفَافٍ وَافٍ أَوْ غَيْرِ وَافٍ فَلَمَّا سَمِعَ ذَلِكَ تَرَكَهُ وَتَبِعَهُ قَالَ فَقَالَ يَا نَبِيَّ اللهِ قُلْتَ قَبْلُ مَنْ طَلَبَ أَخَاهُ فَلْيَطْلُبْهُ بِعَفَافٍ وَافٍ أَوْ غَيْرِ وَافٍ قَالَ نَعَمْ قَالَ يَا نَبِيَّ اللهِ مَا الْعَفَافُ؟ قَالَ غَيْرَ شَاتِمِهِ وَلَا مُتَشِدِّدٍ عَلَيْهِ وَلَا مُتَفَحِّشٍ عَلَيْهِ وَلَا مُؤْذِيهِ قَالَ وَافٍ أَوْ غَيْرِ وَافٍ ؟ قَالَ مُسْتَوْفٍ حَقَّهُ أَوْ تَارِكٌ بَعْضَهُ
