Hadith 8:11
Anas said that Abu Taiba cupped God’s Messenger and he ordered that sa’ of dates be given him, also ordering his people to remit some of his dues.* * Abu Taiba was a client of the B. Haritha. It was the custom for a slave to hand over to his master part of what he earned. Here the Prophet suggests that the masters of Abu Taiba should reduce the amount they took from him. (Bukhari and Muslim.)
وَعَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: حَجَمَ أَبُو طَيْبَةَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأُمِرَ لَهُ بِصَاعٍ مِنْ تَمْرٍ وَأَمَرَ أَهْلَهُ أَنْ يُخَفِّفُوا عَنْهُ مِنْ خراجه
