Surah 104. Al-Humazah
Woe to every slanderer backbiter.
Who gathers wealth and counts it over.
Thinking that his wealth has made him immortal.
By no means. He will be thrown into the Crusher.
I know it's basically impossible to say someone isn't in a religion (much to the chagrin of many a devout and reasonable religious person), but this surah is so specifically against this guy in particular.
