Where do you find allah? Is he considered a living thing?

Allah in the Islamic belief: "Allah  is the only God, creator of the universe, and the judge of humankind." The Qur'an declares "the reality of Allah, His inaccessible mystery, His
various names, and His actions on behalf of His creatures."

Like the god of any religion, Allah is in the minds and hearts of the believers and not a physical entity.
