Qur'an 17:8

عَسَىٰ رَبُّكُمْ أَن يَرْحَمَكُمْ ۚ وَإِنْ عُدتُّمْ عُدْنَا ۘ وَجَعَلْنَا جَهَنَّمَ لِلْكَـٰفِرِينَ حَصِيرًا

“[Then Allāh said], "It is expected, [if you repent], that your Lord will have mercy upon you. But if you return [to sin], We will return [to punishment]. And We have made Hell, for the disbelievers, a prison-bed."”
