Yahya bin al-Jazzar narrates from Sayyiduna Ali (may Allah be pleased with him) concerning a man who handed his wife over to her family. He said: If they accept her, it is one separating (irrevocable) divorce; and if they return her, it is still one divorce and the husband has more right to take her back.
