Atheism has a happy heaven, you stage a false flag attack on your citizens, call it a pearl harbour, then go an murder and rob people in other countries in order to live a rich life and lend money on usury to the looted people, but since it's a scam worse than a pyramid scheme - it begins to eat its own tail and breeds offspring with minds that are more illogical, and criminal, and narrow minded - then the empire falls.
With Islam it's not only happy heaven hereafter, a just earth is created, it is the only empire that has survived through the ages and has continually stood back up after every stumble - read history to realise that the only names in a chain which ultimately prevailed are those of the Prophets who stood on the testimony that there is no other deity except the one God.
