It was narrated from Umm Salamah that the Messenger of Allah (peace be upon him) said: “You refer your disputes to me and I am only human. Perhaps some of you may be more eloquent in presenting your case than others, so I rule in your favor because of what I hear from you. If I pass a judgement in favor of one of you that detracts from his brother’s rights, then he should not take it, because it is a piece of fire that is given to him which he will bring forth on the Day Resurrection.”
Sunan Ibn Majah, Book 13, Hadith 10
