What is the ruling if the wife refuses to take off her clothes during intercourse?

The spouses must satisfy each other's needs in a befitting manner, and shyness in this situation is not praiseworthy. The husband should explain to his wife that she will be rewarded for doing so, and that it is a way to stabilize their marital life and prevent him from looking to others. He should also tell her that her lack of response is a shortcoming in his right, and that this was the practice of the Mothers of the Believers.
