Surah Ali'Imran, Verse 24

ذَٰلِكَ بِأَنَّهُمۡ قَالُواْ لَن تَمَسَّنَا ٱلنَّارُ إِلَّآ أَيَّامٗا مَّعۡدُودَٰتٖۖ وَغَرَّهُمۡ فِي دِينِهِم مَّا كَانُواْ يَفۡتَرُونَ٢٤

dhālika bi-annahum qālū lan tamassanā l-nāru illā ayyāman maʿdūdātin wagharrahum fī dīnihim mā kānū yaftarūna

That is because they say, "Never will the Fire touch us except for [a few] numbered days," and [because] they were deluded in their religion by what they were inventing.
