Musannaf Ibn Abi Shaybah 21485 — Guarantee of clear title (khalas)

Al-Hakam said: A man left a slave girl for his wife and his son. His wife and son sold the slave girl, the buyer had intercourse with her, and she also bore him a child. After that the owner of the slave girl came and sought to take her. The case was brought before Sayyiduna Ali (may Allah be pleased with him), and Sayyiduna Ali (may Allah be pleased with him) said to him: Your wife and your son sold your slave girl, and the buyer has had a child by her; let the sale stand. He said: I adjure you by Allah to judge according to the Book of Allah. Sayyiduna Ali (may Allah be pleased with him) said to that man: Take your slave girl and her child. Then he said to the other man: Take khalas from the woman and her son. When khalas was taken from them, the other man surrendered the sale. * From hadith number 20647 it appears that khalas means the following: if someone sells an item and the buyer begins to use it, and then a rightful claimant to that item appears, the original price of the item is taken from the seller, and an additional compensation is also collected in order to end the dispute.
