There is no reason to believe claims like this without any evidence,
@Taij4an is right it is just slander. There are a lot of nonmuslims on this forum.
The story seems purely constructed to make the person seem like a hypocrite using religion, no real wrongdoing on a personal level to her was shared. Just that she flew out of her country to stay in a hotel to meet a man she met in a sheesha bar and was stood up apparently? It makes no sense.
Sisters should not fall victim to this kind of thing because they should know better then to travel to meet a strange man alone.
Without evidence this shouldnt be entertained.
