He replied:

If the first husband was rightfully compelled to separate from her—for example, because he was neglecting his duties towards her or unjustly harming her by word or deed—then the separation was valid, the second marriage is valid, and she is the second man’s wife. But if he was compelled through beating or imprisonment to separate from her while treating her well, the separation did not take effect. Rather, if she dislikes him while he treats her well, he should be asked to separate from her without being compelled to do so. If he agrees, well and good; otherwise, the woman should be instructed to bear patiently with him, provided there are no grounds permitting annulment of the marriage.

He—may Allah Most High have mercy on him—was asked:

Concerning a man who accused his wife of indecency, although he had seen nothing in her conduct that Islamic law condemns, except that [he] (1) claimed to have sent her to a wedding and then secretly checked on her but did not find her there. She denied this. He then went to her guardians and told them what had happened. They summoned her to meet her husband concerning what had been mentioned, but she refused for fear of being beaten and went to her maternal uncle’s house. The husband subsequently used this as grounds for depriving her of her entitlement, claiming that she had left without his permission. Does this invalidate her entitlement? Does her denial of his allegation warrant censure under Islamic law?

He replied:

Allah Most High says:

“O you who believe, it is not lawful for you to inherit women against their will. Nor should you make life difficult for them in order to take back some of what you have given them, unless they commit a clear indecency.”

Thus, it is not lawful for a man to constrain his wife by restricting her and making life difficult for her
