One of the ancillaries of religion (the Furu' al-Din) which of great importance and has been emphatically ordered to, is the subject of enjoining to what is good and forbidding what is evil. Islam is a school of thought which considers every one responsible for their surroundings and the society they live in and it severely disagrees being indifference, as the Holy Prophet of Islam says: " «كُلُّكُم راعٌ و كُلُّكُم مَسئولٌ عَن رَعيَّتِهِ», all human beings are responsible toward one another. Therefore, it is considered totally wrong if some people claim that everyone has their own religion
