A man asked Sayyiduna Ibn Abbas (may Allah be pleased with them both), saying that he had divorced his wife a hundred times. He said: "You have disobeyed your Lord, and your wife has become separated from you. You did not fear Allah, so that He would make a way out for you and provide for you from where you do not expect." Then he recited this verse: "O Prophet, when you divorce women, divorce them at (the start of) their waiting period (iddah)" [Al-Talaq: 1].
