وَقَالُوا۟ لَن تَمَسَّنَا ٱلنَّارُ إِلَّآ أَيَّامًۭا مَّعْدُودَةًۭ ۚ قُلْ أَتَّخَذْتُمْ عِندَ ٱللَّهِ عَهْدًۭا فَلَن يُخْلِفَ ٱللَّهُ عَهْدَهُۥٓ ۖ أَمْ تَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ
And they say: The Fire (of punishment) will not touch us save for a certain number of days. Say: Have ye received a covenant from Allah - truly Allah will not break His covenant - or tell ye concerning Allah that which ye know not?
