In the first place, we would like to stress that spouses are permitted to look at each other’s naked body, especially when this is done during intimacy. However, being nude in front of each other unnecessarily should be avoided.
Dr. Muzammil H. Siddiqi, former President of the Islamic Society of North America, states that: “There is no `awrah (parts of the body to be hidden) between the husband and wife. The husband and wife can be naked in front of each other. However, Islam urges human beings to observe haya’ or modesty. The Prophet (peace and blessings be upon him) is reported to have said, “The haya’ is part of faith.”
Thus, one should not be nude unnecessarily. The husband and wife can take their clothes off in front of each other to enjoy their sexual relations, but after that they should cover themselves. It is not good to walk around the house naked, even in one’s privacy and not in front of others. It is absolutely haram to be nude in front of other people unless it be before the doctor for medical examination and treatment only.”
