Musannaf Ibn Abi Shaybah

Ibrahim (may Allah have mercy on him) said that if he approaches her before the completion of four months, then three divorces will take place. And if he leaves her for four months, then she will become separated (bainah) with one divorce, and he cannot marry her again until less than the days of ila, that is, two or three months, have passed. Then he may marry her, but he should not approach her for a year. This was also the opinion of Hazrat Saeed (may Allah have mercy on him).
