Narrated Zayd ibn Arqam:
I was sitting with the Prophet (peace_be_upon_him). A man came from the Yemen, and said: Three men from the people of the Yemen came to Ali, quarrelling about a child, asking him to give a decision. They had had sexual intercourse with a woman during a single state of purity.
He said to two of them: Give this child to this man (the third person) with pleasure. But they (refused and) cried loudly. Again he said to two of them: Give the child to the man (the third person) willingly. But they (refused and) cried loudly. He then said: You are quarrelsome partners. I shall cast lots among you; he who receives the lot, will acquire the child, and he shall pay two-thirds of the blood-money to both his companions. He then cast lots among them, and gave the child to the one who received the lot. The Apostle of Allah (peace_be_upon_him) laughed so much that his canine or molar teeth appeared.
