صِدْقهِمْ

Appears 2 times in the Quran. (Root: صدق)
  1. That He may question the truthful of their truth, and He has prepared for the unbelievers a painful punishment.

  2. That Allah may reward the truthful for their truth, and punish the hypocrites if He please or turn to them (mercifully); surely Allah is Forgiving, Merciful.
