Sayyiduna Rukanah bin Abd Yazid (may Allah be pleased with him) said: I had a wife called Suhaymah, and I gave her the battah divorce (a final, irrevocable divorce). Then I came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him), I have given my wife Suhaymah the battah divorce, and by Allah, I intended only one." He (peace and blessings be upon him) asked: "By Allah, did you intend only one?" I said: "Yes, by Allah, I intended only one." So he (peace and blessings be upon him) returned my wife to me on the basis of one divorce.
