It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that I was present with the Messenger of Allah (peace and blessings be upon him) when a man from Yemen came and, relating an incident to the Prophet (peace and blessings be upon him), said: O Messenger of Allah! Three men came to Sayyiduna Ali (may Allah be pleased with him) disputing over a child; all three had had relations with one woman during a single tuhr (period of purity). Sayyiduna Ali (may Allah be pleased with him) said to two of them: "Give up this child willingly." Then he said: "You are partners disputing with one another. Now I will cast lots between you; the one whose name the lot falls on, the child will be his, and he must pay two-thirds of the diyah (blood money) (of the child) to his two remaining companions." So he cast lots, the lot fell on one of them, and he handed the child over to him. On hearing this, the Messenger of Allah (peace and blessings be upon him) smiled until his (peace and blessings be upon him) blessed teeth became visible.
