Surah Faatir, Verse 42
وَأَقْسَمُوا۟ بِٱللَّهِ جَهْدَ أَيْمَٰنِهِمْ لَئِن جَآءَهُمْ نَذِيرٌۭ لَّيَكُونُنَّ أَهْدَىٰ مِنْ إِحْدَى ٱلْأُمَمِ ۖ فَلَمَّا جَآءَهُمْ نَذِيرٌۭ مَّا زَادَهُمْ إِلَّا نُفُورًا
Translation — Sahih International
And they swore by Allah their strongest oaths that if a warner came to them, they would be more guided than [any] one of the [previous] nations. But when a warner came to them, it did not increase them except in aversion.
