(Isra) 17 : 8
عَسَىٰ رَبُّكُمْ أَنْ يَرْحَمَكُمْ ۚ وَإِنْ عُدْتُمْ عُدْنَا ۘ وَجَعَلْنَا جَهَنَّمَ لِلْكَافِرِينَ حَصِيرًا

"Your Lord may show Mercy upon you; but if you are aggressing again, We will also re-tribute, and We have made Hell as a returning place for the disbelievers".

Even if this verse is addressing the Jews in Medina during the time of Messenger, today it is applicable only for the Arabic Quran reading Fujjar who have made their food ‘rejecting Adhikr’. Adhikr is the Mercy mentioned in 65 places such as 2: 105; 4: 113 and 10: 58. So whoever utilizes Adhikr as the Ticket for returning to the Paradise, he will only succeed in the Hereafter. See explanation 2: 39; 6: 26 and 14: 28-30.
