Rituals and Ceremonies in Islam
In ancient times religions were often obsessed with rituals and ceremonies and impurity. It was believed that God required worship be performed in a designated way and that every step must be performed exactly in the prescribed fashion. Religion was infused with the ideas of magic and superstition. Islam still contains much of this thinking much of which is related to the obsession with blood. Animals must be slaughtered in the correct halal way by ritually empowered Muslim men before it can be eaten though the slaughtering of non-Muslims could be done any and every way possible.
