Mukhtasar Muslim

Narrated from Umm al-Mu'mineen Umm Salamah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings of Allah be upon him) heard the noise of disputants at the door of his chamber, so he came out and said: I am only a human being, and people come to me with their disputes, and it may be that one of them is more eloquent in presenting his case than the other, and I think he is telling the truth and so I judge in his favor. So, if I give someone the right of his Muslim brother, then it is only a piece of fire; let him take it or leave it.
