I embraced Islam while I had eight wives. So I mentioned it to the Prophet (ﷺ). The Prophet (said) said: Select four of them.
Abu Dawud said: This tradition has also been narrated to us by Ahmad b. Ibrahim from Hushaim. He said: Qais b. al-Harith instead of al-Harith b. Qais. Ahmad b. Ibrahim said: This is correct, i.e. Qais b. al-Harith.
