Alqamah narrates: A man came to Sayyiduna Ibn Mas'ud (may Allah be pleased with him) and said: I have given my wife ninety-nine divorces, and I asked and was told that she has become separated from me. Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: "Those who told you this wanted a separation between you and her." He said: Then what do you say, may Allah have mercy on you? (The narrator said:) He thought that he would grant him some concession, but he said: "Three divorces separate her from you, and all the rest are transgression."
