Al-Israa • EN-TAFSIR-IBN-ABBAS
﴿ عَسَىٰ رَبُّكُمْ أَن يَرْحَمَكُمْ ۚ وَإِنْ عُدتُّمْ عُدْنَا ۘ وَجَعَلْنَا جَهَنَّمَ لِلْكَٰفِرِينَ حَصِيرًا ﴾
“Your Sustainer may well show mercy unto you; but if you revert [to sinning], We shall revert [to chastising you]. And [remember this:] We have ordained that [in the hereafter] hell shall close upon all who deny the truth.”
(It may be that your Lord will have mercy on you) after that, (but if ye repeat (the crime) We shall repeat (the punishment)) it is also said that this means: if you return to doing good, We will return to bestowing mercy on you, (and We have appointed hell a dungeon) a prison and jail (for the disbelievers).
