Sahih Muslim , Book 10, Hadith 3897 (USC-MSA) ⓘ
Abu Rafi', the freed slave of Allah's Messenger, said: Allah's Messenger took as a loan (the rest of the hadith is the same), but with this variation that he (the Holy Prophet) said: Good amongst the servants of Allah is he who is best in paying off the debt.
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، عَنْ مُحَمَّدِ بْنِ جَعْفَرٍ، سَمِعْتُ زَيْدَ بْنَ أَسْلَمَ، أَخْبَرَنَا عَطَاءُ بْنُ يَسَارٍ، عَنْ أَبِي رَافِعٍ، مَوْلَى رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ اسْتَسْلَفَ رَسُولُ اللَّهِ صلى الله عليه وسلم بَكْرًا . بِمِثْلِهِ غَيْرَ أَنَّهُ قَالَ " فَإِنَّ خَيْرَ عِبَادِ اللَّهِ أَحْسَنُهُمْ قَضَاءً " .
