(the wife of the Prophet) Messenger of Allah ﷺ heard some people quarreling at the door of his dwelling, so he went out to them and said, "I am only a human being, and litigants with cases of dispute come to me, and someone of you may happen to be more eloquent (in presenting his case) than the other, whereby I may consider that he is truthful and pass a judgment in his favor. If ever I pass a judgment in favor of somebody whereby he takes a Muslim's right unjustly, then whatever he takes is nothing but a piece of Fire, and it is up to him to take or leave." (Using translation from Bukhārī 7181)  

أَنَّ أُمَّ سَلَمَةَ زَوْجَ النَّبِيِّ ﷺ أَخْبَرَتْهَا عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ سَمِعَ خُصُومَةً بِبَابِ حُجْرَتِهِ فَخَرَجَ إِلَيْهِمْ فَقَالَ إِنَّمَا أَنَابَشَرٌ فَذَكَرَ مَعْنَاهُ
