I think this is a great funny video. They are young and they just wanted to have some fun. Maybe they exaggerated a little but young people are sometimes unconscious of consequences and in this age the more important is to feel happy, to feel good with life. So why punish the right to be happy? And I don’t think they looked for be offensive to the religion. I think they are so muslims as every other muslim is. Only they made a video that shouldn’t be take so seriously. There are things much worst than five girls dancing mixing pop music and praying and much more offensive to God.
Maybe they will suffer bad consequences from society, maybe they will have difficulties in future life as already they are actually having, maybe family and friends will look at them on a different way. And all this because of a video. Is this necessary? I think not. So, please, let them return to school and make the final exam.
