Kaʿb demanded his debt back from Ibn Abi Hadrad in the Mosque and their voices grew louder till Messenger of Allah ﷺ heard them while he was in his house. He came out to them raising the curtain of his room and addressed Kaʿb, "O Kaʿb!" Kaʿb replied, "Labaik, O Messenger of Allah ﷺ." (He said to him), "Reduce your debt to one half," gesturing with his hand. Kaʿb said, "I have done so, O Allah's Apostle!" On that the Prophet ﷺ said to Ibn Abi Hadrad, "Get up and repay the debt, to him."
أَنَّهُ تَقَاضَى ابْنَ أَبِي حَدْرَدٍ دَيْنًا كَانَ لَهُ عَلَيْهِ فِي الْمَسْجِدِ فَارْتَفَعَتْ أَصْوَاتُهُمَا حَتَّى سَمِعَهَا رَسُولُ اللَّهِ ﷺ وَهْوَ فِي بَيْتِهِ فَخَرَجَ إِلَيْهِمَا حَتَّى كَشَفَ سِجْفَ حُجْرَتِهِ فَنَادَى يَا كَعْبُ قَالَ لَبَّيْكَ يَا رَسُولَ اللَّهِ قَالَ ضَعْ مِنْ دَيْنِكَ هَذَا فَأَوْمَأَ إِلَيْهِ أَىِ الشَّطْرَ قَالَ لَقَدْ فَعَلْتُ يَا رَسُولَ اللَّهِ قَالَ قُمْ فَاقْضِهِ
