The Messenger of Allah ﷺ said: Profit follows responsibility.  

قَالَ رَسُولُ اللَّهِ ﷺ الْخَرَاجُ بِالضَّمَانِ  

I and some people were partners in a slave. I employed him on some work in the absence of one of the partners. He got earnings for me. He disputed me and the case of his claim to his share in the earnings to a judge, who ordered me to return the earnings (i.e. his share) to him. I then came to Urwah ibn az-Zubayr, and related the matter to him. Urwah then came to him and narrated to him a tradition from the Messenger of Allah ﷺ on the authority of Aisha: Profit follows responsibility.  

كَانَ بَيْنِي وَبَيْنَ أُنَاسٍ شَرِكَةٌ فِي عَبْدٍ فَاقْتَوَيْتُهُ وَبَعْضُنَا غَائِبٌ فَأَغَلَّ عَلَىَّ غَلَّةً فَخَاصَمَنِي فِي نَصِيبِهِ إِلَى بَعْضِ الْقُضَاةِ فَأَمَرَنِي أَنْ أَرُدَّ الْغَلَّةَ فَأَتَيْتُ عُرْوَةَ بْنَ الزُّبَيْرِ فَحَدَّثْتُهُ فَأَتَاهُ عُرْوَةُ فَحَدَّثَهُ عَنْ عَائِشَةَ ؓ عَنْ رَسُولِ اللَّهِ ﷺ قَالَ الْخَرَاجُ بِالضَّمَانِ  

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
