Hadith.4812 - Ibn Muskan narrated from Al-Hasan ibn Ziyad, from Abu Abdullah عليه السلام, who said: "Divorce occurs when a man says to his wife, 'Choose (for yourself),' And if she chooses herself, then she is separated from him, and he becomes one of the suitors (khuṭṭāb). But if she chooses her husband, then it is of no consequence. Or (divorce occurs) if he says, 'You are divorced,' then whichever of these he does, she becomes prohibited for him. However, divorce (ṭalāq), annulment (khul'), mutual separation (mubāra'ah), or giving the wife a choice (takhyīr) is not valid except while she is in a state of purity (ṭuhr), without prior intercourse, and in the presence of two witnesses."
