you dont know enough about Islam to post a question like that..
there are no 72 women waiting for sex in heaven (or hell for that matter)... Islam. grants pure (virginal in purity, not about girls who havent had sex).. these beings are created soley for use or people who get to heaven.. we will all have pure beautiful servants.. They are not human.. they are not sex toys.. Also nowhere in the Quran does God/Allah mention any certain number.. I have no idea where 72 was made up from.. anyways.. there is no jealousy in heaven
