Ikrimah (may Allah have mercy on him) narrates from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that Rukanah (may Allah be pleased with him) divorced his wife three times in a single sitting, and he was greatly distressed over it. Then the Messenger of Allah (peace and blessings be upon him) asked him: "How did you divorce her?" Rukanah (may Allah be pleased with him) said: "I gave three divorces." He (peace and blessings be upon him) asked: "In a single sitting?" He said: "Yes." He (peace and blessings be upon him) said: "That is only one; take her back if you wish." So he took her back. Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that divorce is to be given at the time of purity; this is the way people followed, and Allah, the Lord of Might, commanded it: "Divorce them for their waiting period" [Surah al-Talaq: 1].
This chain cannot serve as proof against eight narrators who reported from Sayyiduna Ibn Abbas (may Allah be pleased with them both) his fatwa contrary to it, nor against the report of the children of Rukanah (may Allah be pleased with him) that his divorce was only one.
