(Eternity of Heaven and Hell*)
Some have said, “Hell will not touch us, except for a limited number of days.” Say, “Have you taken such a pledge from God – God never breaks His pledge – or, are you saying about God what you do not know?”
وَقالوا لَن تَمَسَّنَا النّارُ إِلّا أَيّامًا مَعدودَةً قُل أَتَّخَذتُم عِندَ اللَّهِ عَهدًا فَلَن يُخلِفَ اللَّهُ عَهدَهُ أَم تَقولونَ عَلَى اللَّهِ ما لا تَعلَمونَ
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
*2:80-82 It is an established belief among corrupted Muslims that they will suffer in Hell only in proportion to the number of sins they had committed, then they will get out of Hell and go to Heaven. They also believe that Muhammad will intercede on their behalf, and will take them out of Hell. Such beliefs are contrary to the Quran (Appendix 8).
