وَٱلَّذِينَ سَعَوْ فِىٓ ءَايَـٰتِنَا مُعَـٰجِزِينَ أُولَـٰٓئِكَ لَهُمْ عَذَابٌ مِّن رِّجْزٍ أَلِيمٌ

Wallatheena saAAaw fee ayatinamuAAajizeena ola-ika lahum AAathabun minrijzin aleem

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