Quran 40:50 — Forgiver (Ghafer)

They will say, "Did you not receive your messengers who delivered to you clear messages?" They will reply, "Yes we did." They will say, "Then implore (as much as you wish); the imploring of the disbelievers is always in vain."

[40:49] Those in the hellfire will say to the guardians of Hell, "Call upon your Lord to reduce the retribution for us, for even one day."

[40:51] Most assuredly, we will give victory to our messengers and to those who believe, both in this world and on the day the witnesses are summoned.
