Here (i.e. in Mecca) there was a man called Nawwas and he had camels suffering from the disease of excessive and unquenchable thirst. Ibn ʿUmar went to the partner of Nawwas and bought those camels. The man returned to Nawwas and told him that he had sold those camels. Nawwas asked him, "To whom have you sold them?" He replied, "To such and such Sheikh." Nawwas said, "Woe to you; By Allah, that Sheikh was Ibn ʿUmar." Nawwas then went to Ibn ʿUmar and said to him, "My partner sold you camels suffering from the disease of excessive thirst and he had not known you." Ibn ʿUmar told him to take them back. When Nawwas went to take them, Ibn ʿUmar said to him, "Leave them there as I am happy with the decision of Messenger of Allah ﷺ that there is no oppression . "  

إِنَّ شَرِيكِي بَاعَكَ إِبِلاً هِيمًا وَلَمْ يَعْرِفْكَ قَالَ فَاسْتَقْهَا قَالَ فَلَمَّا ذَهَبَ يَسْتَاقُهَا فَقَالَ دَعْهَا رَضِينَا بِقَضَاءِ رَسُولِ اللَّهِ ﷺ لاَ عَدْوَى سَمِعَ سُفْيَانُ عَمْرًا
