Questions atheists usually ask about Allah might vary but, they're predictable. Consider these: 1. Is there evidence God Exists? 2. How can we prove there is a God? 3. Where is God? 4. What is the origin of God? Where did He come from? and more.

Hajj and Tawheed: Hajj is to set out for Makkah to worship Allah by performing certain religious rights in accordance with the Prophet's (peace and blessings be upon him) Sunnah. It is a time in which to call upon Allah to purify the self from any worship to anyone other than him. This booklet explains the basic rights of Hajj. It also notes that the tawheed of Allah requires the Muslim to follow the perfect way of worship, demonstrated by Muhammad (peace and blessings be upon him) and as understood by the Sahaabah who were the best of mankind.
