Trigger warning: criticism of Islam.
The way to follow the Prophet Muhammad is to emulate him in how he worshipped and lived generally.
All the Muslims are eventually going to heaven, but only those who followed the way of the Prophet unadulterated to their greatest ability are going to be unpunished.
We all know that Prophet Muhammad married a 6-year-old, and had sex with her when she was 9. So if you want to go to the Muslim heaven unpunished, you have to have sex with prepubescent children.
