Abdullah bin Ali bin Yazid bin Rukanah (may Allah have mercy on him) narrates from his father, and he from his grandfather (may Allah be pleased with him), that he gave his wife the battah divorce (a final, irrevocable divorce) and came to the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) asked: "What did you intend by it?" He said: One divorce. He (peace and blessings be upon him) said: "By Allah?" He said: By Allah. He (peace and blessings be upon him) said: "It is as you intended."
