And they say, "Never will the Fire touch us, except for a few days.

وَقَالُوا لَن تَمَسَّنَا النَّارُ إِلَّا أَيَّامًا مَّعْدُودَةً ۚ قُلْ أَتَّخَذْتُمْ عِندَ اللَّهِ عَهْدًا فَلَن يُخْلِفَ اللَّهُ عَهْدَهُ ۖ أَمْ تَقُولُونَ عَلَى اللَّهِ مَا لَا تَعْلَمُونَ

Sahih International

And they say, "Never will the Fire touch us, except for a few days." Say, "Have you taken a covenant with Allah ? For Allah will never break His covenant. Or do you say about Allah that which you do not know?"

Quran (2:80)
