Mishkat al-Masabih 3770

Umm Salama told on the Prophet’s authority about two men, who brought a dispute before him about inheritances, but had no proof beyond their claim. He said, “If I give a decision in favour of one respecting what is rightly his brother’s I am allotting him only a portion of hell.” Thereupon both the men said, “Messenger of God, this right of mine may go to my brother,” but he replied, "No; rather go and divide it up, aiming at what is right, then draw lots, and let each of you consider the other to have what is legitimately his.” In a version he said, “I judge between you only by my opinion regarding matters about which no revelation has been sent down to me.” Abu Dawud transmitted it.
