Ref. No. 41/ 1032
In the name of Allah the most gracious the most merciful
The answer to your question is as follows:
Islam gave the husband the right to have sex with his wife whenever he wants, and if the wife refuses to engage in sexual relationship with her husband without any genuine reason, the husband has right o force his wife to have sex with her. This is not called rape. However, Islam advised that the sexual intercourse between husband and wife should be conducted with intimacy and love.
Moreover, if she is in menstruation or has a contagious disease then she has the right to refrain from her husband.
And Allah knows best
