Maqil bin Yasar reported,

He said that this verse was revealed concerning him. He said, "I gave a sister of mine in marriage to a man, and he divorced her. When her waiting period ended, he came back to propose to her again. I said to him, 'I married her to you, gave her a bed, and honored you, then you divorced her, and now you come to propose to her again? No, by Allah, she will never return to you.' He was a decent man, and the woman wanted to return to him. So Allah revealed this verse, 'Do not prevent them' [Baqarah 2:232]."I said, "Now I will do it, Messenger of Allah."So he married her to him.
