وَالَّذِيْنَ سَعَوْ فِيْٓ اٰيٰتِنَا مُعٰجِزِيْنَ اُولٰۤىِٕكَ لَهُمْ عَذَابٌ مِّنْ رِّجْزٍ اَلِيْمٌ

Wal-lażīna sa‘au fī āyātinā mu‘ājizīna ulā'ika lahum ‘ażābum mir rijzin alīm(un).

"But those who strive against Our verses [seeking] to cause failure - for them will be a painful punishment of foul nature."
