The Believers - 23:100 "So that I may do righteous deeds in that which I have forsaken."No. This is but a word he utters. There is a barrier behind them until the Day of Resurrection."
The disbelievers will not be turned back / will not be given another chance:
The Believers/23:99 "When death comes to one of them, he says: "My Lord, bring me back."
The Believers/23:100 "So that I may do righteous deeds in that which I have forsaken."No. This is but a word he utters. There is a barrier behind them until the Day of Resurrection."

The Prostration/32:29 "Say, "On the Day of Victory, belief will not avail the disbelievers, nor will they be given another chance."
The Prostration/32:12 "If you had only seen the guilty when they bowed their heads before their Lord: "Our Lord, we have seen and heard, so turn us back so that we may act righteously; now we have firmly believed."
The Prostration/32:13 If We had willed, We could have given guidance to everyone, but My promise has come true that I will fill Hell with a portion of the jinn and mankind.
