Sahih al-Bukhari, Hadith 2710 ⓘ
Narrated `Abdullah bin Ka`b: That Ka`b bin Malik told him that in the lifetime of Allah's Messenger he demanded his debt from Ibn Abu Hadrad in the Mosque. Their voices grew louder till Allah's Messenger heard them while he was in his house. So he lifted the curtain of his room and called Ka`b bin Malik saying, "O Ka`b!" He replied, "Labbaik! O Allah's Messenger!" He beckoned to him with his hand suggesting that he deduct half the debt. Ka`b said, "I agree, O Allah's Messenger!" Allah's Messenger then said (to Ibn Abu Hadrad), "Get up and pay him the rest."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ، أَخْبَرَنَا يُونُسُ،. وَقَالَ اللَّيْثُ حَدَّثَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ كَعْبٍ، أَنَّ كَعْبَ بْنَ مَالِكٍ، أَخْبَرَهُ أَنَّهُ، تَقَاضَى ابْنَ أَبِي حَدْرَدٍ دَيْنًا كَانَ لَهُ عَلَيْهِ فِي عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي الْمَسْجِدِ، فَارْتَفَعَتْ أَصْوَاتُهُمَا حَتَّى سَمِعَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم وَهْوَ فِي بَيْتٍ، فَخَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِلَيْهِمَا حَتَّى كَشَفَ سِجْفَ حُجْرَتِهِ، فَنَادَى كَعْبَ بْنَ مَالِكٍ فَقَالَ " يَا كَعْبُ ". فَقَالَ لَبَّيْكَ يَا رَسُولَ اللَّهِ. فَأَشَارَ بِيَدِهِ أَنْ ضَعِ الشَّطْرَ. فَقَالَ كَعْبٌ قَدْ فَعَلْتُ يَا رَسُولَ اللَّهِ. فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " قُمْ فَاقْضِهِ ".
