Looking at your wife when she is nude is totally permissible and halal. Allah has given you this privilege as a gift from him as you are human and you need to fulfill your desires through this halal way! Not looking at her would mean that you are an innovator and prohibiting what Allah had made halal for you and this is a sign of the innovators and fanatics.

I’ve started practicing Islam a lot. One of the things I’m now doing on a regular basis is lowering the gaze from semi nude women. Looking at them corrupts my heart. My worry is how will I cope, looking at my wife after marriage during intercourse or times of privacy. Although, there’s nothing wrong in it, she’s still a woman and those feelings of corruption could come. Thanks
