Sahih Bukhari Volume 3, Book 44, Hadith 2419

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ، أَخْبَرَنَا يُونُسُ، عَنِ الزُّهْرِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ كَعْبِ بْنِ مَالِكٍ، عَنْ كَعْبٍ ـ رضى الله عنه ـ أَنَّهُ تَقَاضَى ابْنَ أَبِي حَدْرَدٍ دَيْنًا كَانَ لَهُ عَلَيْهِ فِي الْمَسْجِدِ، فَارْتَفَعَتْ أَصْوَاتُهُمَا حَتَّى سَمِعَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم 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 ‏"‏‏.‏

Narrated By 'Abdullah bin Ka'b bin Malik : Ka'b demanded his debt back from Ibn Abi Hadrad in the Mosque and their voices grew louder till Allah's Apostle heard them while he was in his house. He came out to them raising the curtain of his room and addressed Ka'b, "O Ka'b!" Ka'b replied, "Labaik, O Allah's Apostle." (He said to him), "Reduce your debt to one half," gesturing with his hand. Kab said, "I have done so, O Allah's Apostle!" On that the Prophet said to Ibn Abi Hadrad, "Get up and repay the debt, to him."
