A man bought a slave, and he remained with him as long as Allah wished him to remain. He then found defect in him. He brought his dispute with him to the Prophet ﷺ and he returned him to him. The man said: Messenger of Allah, my slave earned some wages. The Messenger of Allah ﷺ then said: Profit follows responsibility. Abu Dawud said: This chain of narrators (of this version) is not reliable.  

أَنَّ رَجُلاً ابْتَاعَ غُلاَمًا فَأَقَامَ عِنْدَهُ مَا شَاءَ اللَّهُ أَنْ يُقِيمَ ثُمَّ وَجَدَ بِهِ عَيْبًا فَخَاصَمَهُ إِلَى النَّبِيِّ ﷺ فَرَدَّهُ عَلَيْهِ فَقَالَ الرَّجُلُ يَا رَسُولَ اللَّهِ قَدِ اسْتَغَلَّ غُلاَمِي فَقَالَ رَسُولُ اللَّهِ ﷺ الْخَرَاجُ بِالضَّمَانِ  

[Machine] A man purchased a slave and took advantage of him, but then discovered or saw a defect in him, so he returned him due to the defect. The seller said, "The fault of my slave." The Prophet (peace and blessings be upon him) said, "The guarantee is determined by the fault."  

أَنَّ رَجُلًا ابْتَاعَ غُلَامًا فَاسْتَغَلَّهُ ثُمَّ وَجَدَ أَوْ رَأَى بِهِ عَيْبًا فَرَدَّهُ بِالْعَيْبِ فَقَالَ الْبَائِعُ غَلَّةُ عَبْدِي فَقَالَ النَّبِيُّ ﷺ الْغَلَّةُ بِالضَّمَانِ  

[Machine] A man bought a servant during the time of the Prophet Muhammad ﷺ. The servant had a defect that the man was not aware of, and he took advantage of him. Later, when the man discovered the defect, he returned the servant and argued with him before the Prophet ﷺ. The man said, "O Messenger of Allah, he was in my possession for a long time." The Messenger of Allah ﷺ then said, "The defective merchandise is under warranty."  

أَنَّ رَجُلًا اشْتَرَى غُلَامًا فِي زَمَنِ النَّبِيِّ ﷺ وَبِهِ عَيْبٌ لَمْ يُعْلِمْ بِهِ فَاسْتَغَلَّهُ ثُمَّ عَلِمَ الْعَيْبَ فَرَدَّهُ فَخَاصَمَهُ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّهُ اسْتَغَلَّهُ مُنْذُ زَمَانٍ فَقَالَ رَسُولُ اللَّهِ ﷺ «الْغَلَّةُ بِالضَّمَانِ»
