Chapter: Someone for whom a favour is done and he repays

بَابُ مَنْ صُنِعَ إِلَيْهِ مَعْرُوفٌ فَلْيُكَافِئْهُ
Al-Adab Al-Mufrad 216
Ibn 'Umar reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Anyone who seeks refuge in Allah will find refuge with Him. Anyone who asks from Allah will be receive. Anyone who does a favour should repay it. If you do not find anything, then make supplication for the doer of the favour so that he knows that you have repaid him."
حَدَّثَنَا مُسَدَّدٌ، قَالَ‏:‏ حَدَّثَنَا أَبُو عَوَانَةَ، عَنِ الأَعْمَشِ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ عُمَرَ قَالَ‏:‏ قَالَ رَسُولُ اللهِ صلى الله عليه وسلم‏:‏ مَنِ اسْتَعَاذَ بِاللَّهِ فَأَعِيذُوهُ، وَمَنْ سَأَلَ بِاللَّهِ فَأَعْطُوهُ، وَمَنْ أَتَى إِلَيْكُمْ مَعْرُوفًا فَكَافِئُوهُ، فَإِنْ لَمْ تَجِدُوا فَادْعُوا لَهُ، حَتَّى يَعْلَمَ أَنْ قَدْ كَافَأْتُمُوهُ‏.‏
