Hadith.4599 - Yunus ibn Abdul Rahman reported:
I asked Imam Ali ibn Musa Ar-Ridha (as) about a man who married a woman in Mut'ah (temporary marriage). Later, her family came to know about it, and they married her off to another man in a public marriage, although she was a truthful woman.
Imam (as) said: "She must not allow her new husband to approach her until her waiting period ('iddah) and contract have ended."
I said: "What if her contract specifies a term of one year, and her new husband cannot wait that long?"
Imam (as) said: "Then her husband should fear Allah (swt) and waive the remaining time for her. Indeed, she has been put to trial, and this world is a place of peace, and believers live in taqiyyah (dissimulation)."
I asked: "What if he waives the remaining days for her, and her waiting period ends? What should she do?"
Imam (as) said: "When she meets her new husband, she should say: 'O man, my family forced me and married me off without consulting me. But now, I am pleased. So, let us begin today with a new, proper marriage between us.'"
I also asked Al-Ridha (as): "What about a woman who marries in Mut'ah, and after her contract ends, she marries another man before completing her waiting period?"
Imam (as) said: "What concern is it to you? The sin of that act is upon her."
