Sahih Muslim · Book 12: The Book of Zakat · What a slave spends of his master's wealth
'Umair, the freed slave of Abi'l-Lahm, said:
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ ، حَدَّثَنَا حَاتِمٌ، - يَعْنِي ابْنَ إِسْمَاعِيلَ - عَنْ يَزِيدَ، - يَعْنِي ابْنَ أَبِي عُبَيْدٍ - قَالَ سَمِعْتُ عُمَيْرًا ، مَوْلَى آبِي اللَّحْمِ قَالَ أَمَرَنِي مَوْلاَىَ أَنْ أُقَدِّدَ، لَحْمًا فَجَاءَنِي مِسْكِينٌ فَأَطْعَمْتُهُ مِنْهُ فَعَلِمَ بِذَلِكَ مَوْلاَىَ فَضَرَبَنِي فَأَتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَذَكَرْتُ ذَلِكَ لَهُ فَدَعَاهُ . فَقَالَ " لِمَ ضَرَبْتَهُ " . فَقَالَ يُعْطِي طَعَامِي بِغَيْرِ أَنْ آمُرَهُ . فَقَالَ " الأَجْرُ بَيْنَكُمَا " .
My master commanded me to cut some meat in strips; (as I was doing it) a poor man came to me and I gave him some of it to eat. My master came to know of that, and he beat me. I came to the Messenger of Allah (ﷺ) and narrated it to him. He (the Holy Prophet) summoned him and said: Why did you beat him? He (Abi'l-Lahm) said: He gives away my food without being commanded to do so. Upon this he (the Holy Prophet) said: The reward would be shared by you two.
