All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.

All the reasons which you mentioned about the husband of your friend which made him suspect his wife are not sound reasons for that suspicion. Most likely, the feeling of this husband is mixed with whispers and abnormal condition. Therefore, he is obliged to fear Allaah and avoid suspicion in such matters, as the Prophet said: "Beware of suspicion, for suspicion is the worst of false tales."

For more benefit on a husband suspecting his wife, please refer to Fataawa 87877 and 89820.

Therefore, we advise that wife to be patient and endeavour to remove the doubt of her husband about her, and she should try to comfort him and clarify to him that the suspicion which is based on illusion or unrealistic reasons is forbidden.

As regards the husband not willing to have children with her, then we have clarified in Fatwa 81310 that the husband has no right to resort to coitus interruption (withdrawing before ejaculation) except with her consent because both of them have the right to have children and this is one of the objectives of marriage.

Allaah Knows best.
