Ata (may Allah have mercy on him) said: A man who had said to his wife 'Habluki ala gharibiki' (your rope is on your withers) was brought to Sayyiduna Umar bin al-Khattab (may Allah be pleased with him). He said to Sayyiduna Ali (may Allah be pleased with him): Judge between them. So Sayyiduna Ali (may Allah be pleased with him) ruled it as three divorces.
The Shaykh said: This does not contradict the narration of Malik; it is as though Sayyiduna Umar (may Allah be pleased with him) counted it as one, as he did with al-battah, while Sayyiduna Ali (may Allah be pleased with him) counted it as three. It is also possible that they all considered it three, for a wife with whom the marriage had been consummated.
