Muslims should refer back to the Quran and hadiths. The truth is Islam is far more simple than what people have made it out to be.The Prophet said to describe his sunnah "its night is like its day". What's allowed and what's prohibited have been made clear. But of course not everyone does so..sadly preferring to make their own interpretations of whats haraam and halaal and causing much debating, divisions and disunity =(
