The Sharia Perspective on Sharing Photographs for Marriage Proposals

Yes, it is absolutely permissible, and there is no harm in it. In fact, a suitor is allowed to see a woman even without her knowing. However, my suggestion is that you should not send a photo until your guardian (Wali) has approved the suitor. The reason for this is to avoid a situation where a man looks at you and rejects you, then moves on to look at someone else and rejects them too. It is not appropriate for photos of Hijabi or Niqabi girls to be circulated or kept in this manner. Only a truly serious person should be allowed to see the photo.
