The muslims cannot take it if somebody make them look like fools. Thats because they insist on performing silly rituals which really have nothing to do with the Belief in the Creator.
Its up to the individual. This thing is up to you. All faith.
If there is doubt about the after life, just look up some you tube videos about those who died momentarily. There were books sbout it too. And CNN has a documentary by gupta. All went through a life record which lasted moments.
One of the moslems' scripture books, the quran, mentions crap like the sun setting in a muddy puddle or that shooting stars are fiery darts thrown at djinns by allah.
