Surah Al-Baqarah (The Cow), Verse 80

وَقَالُوْا لَنْ تَمَسَّنَا النَّارُ اِلَّاۤ اَیَّامًا مَّعْدُوْدَةً قُلْ اَتَّخَذْتُمْ عِنْدَ اللّٰهِ عَهْدًا فَلَنْ یُّخْلِفَ اللّٰهُ عَهْدَهٗۤ اَمْ تَقُوْلُوْنَ عَلَی اللّٰهِ مَا لَا تَعْلَمُوْنَ ۟

Wa qaaloo lan tamassanan Naaru illaaa ayyaamam ma'doo dah; qul attakhaztum 'indal laahi 'ahdan falai yukhlifal laahu 'ahdahooo am taqooloona 'alal laahi maa laa ta'lamoon

“And they say: "The Fire shall not touch us but for a few numbered days:" Say: "Have ye taken a promise from Allah, for He never breaks His promise? or is it that ye say of Allah what ye do not know?"”
