Whoever denies the Creator or refuses to worship Him, or joins others in worship with Him, deserves the most severe punishment, because for a man to deny his Creator, or refuse to worship Him, or join others in worship with Him, is the most serious of human sins, the most abhorrent of beliefs and the worst deviation. If a person is like this, there is no value in any good deed that he does. The atheist who does deeds that are good in his own eyes, and does whatever good deeds he can for his society, is like a man who kills his father and mother and takes good care of dogs. Does it not make sense that he should be punished and that his good treatment of dogs should not count for anything? The most important rights are the rights of Allaah, which are that He should be acknowledged and worshipped.
