Question: Is it permissible, according to the Sharee’ah, for a woman to look at the entire body of her husband, and for him to look at her with the intention of seeking enjoyment in that which is halaal?
Response: It is permissible for a woman to look at the entire body of her husband, and it is permissible for the husband to look at the entire body of his wife without going into much detail [here], as Allaah (Subhaanahu wa Ta’aala) says:
{And those who guard their chastity. Except from their wives or that their right hands possess, for then, they are free from blame. But whoever seeks beyond that, then those are the transgressors}, [Soorah al-Mu.minoon, Aayah 5-7]
