Al-Isra 17:8

AAasa rabbukum an yarhamakumwa-in AAudtum AAudna wajaAAalna jahannama lilkafireenahaseera

[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."

May be your Lord would bestow mercy upon you. But if you do this again, We shall do that again, and We have made Jahannam (Hell) a prison for the disbelievers.”
