Yahya related to me from Malik from Yahya ibn Said and from Yazid ibn Abdullah ibn Qusayt al-Laythi that Said ibn al-Musayyab said, ''Umar ibn al-Khattab said, 'If a woman is divorced and has one or two periods and then stops menstruating, she must wait nine months. If it is clear that she is pregnant, that is that. If not, she must do an idda of three months after the nine, and then she is free to marry.' "
