Question: What is the ruling regarding looking at pictures of women in newspapers, magazines and the like?
Response: It is not for the Muslim to look at the faces of women and nor anything of their ‘awrah; not in magazines and nor other than them for that which exists therein causes fitnah. Rather, it is obligatory upon him to divert his sight from these (pictures) in accordance with the generality of the Sharee’ah evidences prohibiting this out of fear of [falling into] any fitnah; as one diverts his sight from the women on the street and other places.
And with Allaah lies all the success, and may Allaah send prayers and salutations upon our Prophet Muhammad (sal-Allaahu ‘alayhi wa sallam) and his family and his companions.
