Al-An'am - 6:21

وَمَنْ أَظْلَمُ مِمَّنِ افْتَرَى عَلَى اللّهِ كَذِبًا أَوْ كَذَّبَ بِآيَاتِهِ إِنَّهُ لاَ يُفْلِحُ الظَّالِمُونَ
[6:21]
And who is more unjust than he who forges a lie against Allah or (he who) gives the lie to His communications; surely the unjust will not be successful.
Who doth more wrong than he who inventeth a lie against Allah or rejecteth His signs? But verily the wrong-doers never shall prosper.
Who doth greater wrong than he who inventeth a lie against Allah or denieth His revelations? Lo! the wrongdoers will not be successful.
