Narrated Zayd ibn Arqam: Three persons were brought to Ali (Allah be pleased with him) when he was in the Yemen. They and sexual intercourse with a woman during a single state of purity. He asked two of them: Do you acknowledge this child for this (man)? They replied: No. He then put this (question) to all of them. Whenever he asked two of them, they replied in the negative. He, therefore, cast a lot among them, and attributed the child to the one who received the lot. He imposed two-third of the blood-money (i. e. the price of the mother) on him. This was then mentioned to the Prophet ﷺ and he laughed so much that his molar teeth appeared.

Narrated Zayd ibn Arqam: I was sitting with the Prophet ﷺ. 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 Messenger of Allah ﷺ laughed so much that his canine or molar teeth appeared.
