باب التَّقَاضِي وَالْمُلاَزَمَةِ فِي الْمَسْجِدِ
Sahih al-Bukhari 457

Narrated Ka`b:

In the mosque l asked Ibn Abi Hadrad to pay the debts which he owed to me and our voices grew louder. Allah's Messenger (ﷺ) heard that while he was in his house. So he came to us raising the curtain of his room and said, "O Ka`b!" I replied, "Labaik, O Allah's Messenger (ﷺ)!" He said, "O Ka`b! reduce your debt to one half," gesturing with his hand. I said, "O Allah's Messenger (ﷺ)! I have done so." Then Allah's Apostle said (to Ibn Abi Hadrad), "Get up and pay the debt to him."

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، قَالَ حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ، قَالَ أَخْبَرَنَا يُونُسُ، عَنِ الزُّهْرِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ كَعْبِ بْنِ مَالِكٍ، عَنْ كَعْبٍ، 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 ‏"‏‏.‏ وَأَوْمَأَ إِلَيْهِ أَىِ الشَّطْرَ قَالَ لَقَدْ فَعَلْتُ يَا رَسُولَ اللَّهِ‏.‏ قَالَ ‏"‏ قُمْ فَاقْضِهِ ‏"‏‏.‏
