Ka'b bin Malik said that in the time of the Messenger of Allah ﷺ he made demand in the mosque for payment of a debt due to him from Ibn Abi Hadrad, and their voices rose till the Messenger of Allah ﷺ, who was in his house, heard them. The Messenger of Allah ﷺ then went out to them and, removing the curtain of his apartment, he called to Ka'b bin Malik, addressing:
"Ka'b!" He said: "At your service, Messenger of Allah." Thereupon he made a gesture with is hand indicating: Remit half the debt due to you. Ka'b said: "I shall do so, Messenger of Allah." The Prophet ﷺ then said: "Get up and discharge"

حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ كَعْبِ بْنِ مَالِكٍ، أَنَّ كَعْبَ بْنَ مَالِكٍ، أَخْبَرَهُ أَنَّهُ، تَقَاضَى ابْنَ أَبِي حَدْرَدٍ دَيْنًا كَانَ لَهُ عَلَيْهِ فِي عَهْدِ رَسُولِ اللَّهِ ﷺ فِي الْمَسْجِدِ فَارْتَفَعَتْ أَصْوَاتُهُمَا حَتَّى سَمِعَهُمَا رَسُولُ اللَّهِ ﷺ وَهُوَ فِي بَيْتِهِ فَخَرَجَ إِلَيْهِمَا رَسُولُ اللَّهِ ﷺ حَتَّى كَشَفَ سِجْفَ حُجْرَتِهِ وَنَادَى كَعْبَ بْنَ مَالِكٍ فَقَالَ " يَا كَعْبُ " . فَقَالَ لَبَّيْكَ يَا رَسُولَ اللَّهِ . فَأَشَارَ لَهُ بِيَدِهِ أَنْ ضَعِ الشَّطْرَ مِنْ دَيْنِكَ قَالَ كَعْبٌ قَدْ فَعَلْتُ يَا رَسُولَ اللَّهِ . قَالَ النَّبِيُّ ﷺ " قُمْ فَاقْضِهِ " .
