Surah Saba — Ayah 5 (34:5)
وَٱلَّذِينَ سَعَوۡ فِيٓ ءَايَٰتِنَا مُعَٰجِزِينَ أُوْلَٰٓئِكَ لَهُمۡ عَذَابٞ مِّن رِّجۡزٍ أَلِيمٞ ٥
English translation (Saheeh International)
But those who strive against Our verses [seeking] to cause failure1 - for them will be a painful punishment of foul nature.
- - i.e., to undermine their credibility in order to defeat the Prophet (ﷺ).
Brief commentary
As for those who strove to falsify all the verses Allah revealed, and said regarding them, “It is sorcery!” and said regarding My Messenger, “He is a fortune-teller, a sorcerer, and a poet”, they will receive the worst and severest punishment on the Day of Judgement.
