Hadith 5070
Lady Zainab (may Allah be pleased with her) narrates from Lady Umm Salamah (may Allah be pleased with her) that the Prophet Muhammad (peace be upon him) said: I am a human being. You people bring your disputes to me. Sometimes, one of you may be more eloquent in presenting his case than the other, and I give a judgment in his favor based on what I hear. So, if I give someone a right that belongs to his brother, he should not accept it, for I have only cut out a piece of Hell for him.
