وَٱلَّذِينَ سَعَوۡ فِيٓ ءَايَٰتِنَا مُعَٰجِزِينَ أُوْلَٰٓئِكَ لَهُمۡ عَذَابٞ مِّن رِّجۡزٍ أَلِيمٞ
English translation: But those who strive against Our Verses (to) cause failure those for them (is) a punishment of foul nature painful
Transliteration: wa-alladhina sa'aw fi ayatina mu'ajizina ulaika lahum adhabun min rij'zin alimun
