What is the ruling on looking at a picture of one's niqab-wearing fiancée after having seen her in person and being satisfied with her, given that some scholars permit uncovering the face when there is no fear of temptation, and would this be considered a temptation if the suitor is determined to marry her and does not seek to see anyone else?

The basic principle is that it is impermissible to look at a non-mahram woman. An exception to this is the suitor looking at the face and hands of his fiancée, so that he may be clear [about his decision]. One instance of looking is sufficient for this purpose. If the objective is not achieved, then repetition is permissible. Once the objective is achieved, one must refrain from looking, because she remains a non-mahram until the marriage contract is finalized. Indeed, the suitor's gaze might pose a greater danger due to the potential for laxity that could lead both parties to something more serious. Repeatedly looking at the fiancée is a strong presumption for the occurrence of temptation and the arousal of desire; therefore, it is impermissible as a means of preventing corruption. This ruling applies to direct viewing and to viewing images.
