وَالَّذِينَ سَعَوْا فِي آيَاتِنَا مُعَاجِزِينَ أُوْلَئِكَ لَهُمْ عَذَابٌ مِّن رِّجْزٍ أَلِيمٌ
[34:5]
And (as for) those who strive hard in opposing Our communications, these it is for whom is a painful chastisement of an evil kind.
But those who strive against Our Signs, to frustrate them,- for such will be a Penalty,- a Punishment most humiliating.
But those who strive against Our revelations, challenging (Us), theirs will be a painful doom of wrath.
