34:5
وَٱلَّذِينَ سَعَوْ فِىٓ ءَايَٰتِنَا مُعَٰجِزِينَ أُو۟لَٰٓئِكَ لَهُمْ عَذَابٌۭ مِّن رِّجْزٍ أَلِيمٌۭ
Wallazeena sa'aw feee aayaatinaa mu'aajizeena ulaaa 'ika lahum 'azaabum mir irjzin aleem
But those who strive against Our verses [seeking] to cause failure - for them will be a painful punishment of foul nature.
