Ibrahim narrates from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that a man came to him who had given his wife two divorces. He had said (to her): You are forbidden to me. Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) said: I will not return your wife to you.
(b) It is narrated from Sayyiduna Ali and Zayd bin Thabit (may Allah be pleased with them both) that by saying the words "bariyyah" (released), "al-battah" (definitive) and "haram" (forbidden), three divorces take place.
