Surah Saba, Verse 5

وَٱلَّذِينَ سَعَوۡ فِيٓ ءَايَٰتِنَا مُعَٰجِزِينَ أُوْلَٰٓئِكَ لَهُمۡ عَذَابٞ مِّن رِّجۡزٍ أَلِيمٞ٥

wa-alladhīna saʿaw fī āyātinā muʿājizīna ulāika lahum ʿadhābun min rij'zin alīmun

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