Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "I am a human being. It is possible that one of you may be more eloquent in presenting his case than another, so if I give a judgment in his favor which actually belongs to his brother, then I have only cut out a piece of Hellfire for him."
