Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Umm Salamah (may Allah be pleased with her) that two men from the Ansar came to the Prophet (peace and blessings be upon him) disputing over inheritance. They had no witnesses. The Prophet (peace and blessings be upon him) said: "You bring your disputes to me, but I am only a human being like you. Perhaps one of you may be more eloquent in presenting his argument than the other, so I judge between you according to what I hear. So, if I decide in favor of someone, granting him a right that belongs to his brother, he should not take it, for in fact, it is a piece of fire, which will be hung around his neck on the Day of Judgment." Hazrat Umm Salamah (may Allah be pleased with her) says that upon hearing this, both of them began to weep, and each said to the other, "My right is for my brother." The Prophet (peace and blessings be upon him) said: "Now that you have done this, go and divide it among yourselves, intend to do what is right, and then draw lots between yourselves. Then each of you should make his share lawful for his brother."
