[49:15] Mu'mens (believers) are those who believe in GOD and His messenger, then attain the status of having no doubt whatsoever, and strive with their money and their lives in the cause of GOD. These are the truthful ones.

[9:101] Among the Arabs around you, there are hypocrites. Also, among the city dwellers, there are those who are accustomed to hypocrisy. You do not know them, but we know them. We will double the retribution for them, then they end up committed to a terrible retribution.
