That I might do righteousness in that which I left behind." No! (23:100)

Almuntakhab Fi Tafsir Alquran Alkarim

He says: If given the chance I may be able to do all I have neglected and left undone and imprint my deeds with wisdom and piety. Never. But this is a wish he expresses in words! Once the souls have been disembodied and crossed to the other world, it is then a one - way journey with no return. Behind them there is an impassable barrier barricading the passage back until the Day of Resurrection when people are then restored to life

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(23:100) which I have left: I hope I will now do righteous deeds. " *90 -By no means! *91 it is a mere saying that he is uttering: *92 for now there is a barrier between the dead (and the world which they have left) up to the Day *93 when they shall be raised up again.

That I might do righteousness in that which I left behind." No! meaning

*90) It occurs at several places in the Qur'an that each of the criminals, after his death till his entry into Hell, and even after that, will plead again and again: "Lord, send me back to the world: I will no more disobey Thee: I will now do righteous deeds." See Al-An`am (VI):27, 28, Al-A`araf (VII): 53, Ibrahim (X 1 V): 44, 45, Ash-Shu`ara' (XXVI):102, AI-Fatir (XXXV): 37, Az-Zumar (XXXIX): 58, 59, AI-Mu'min (XL): 10-12, and Ash-Shura (XLII): 44 along with the relevant E.N.'s.
*91) That is, "He will never be sent back nor given another opportunity, for in that case the test and vial for which man is sent m this world becomes meaningless." For further explanation, see Al-Baqarah (II): 210 and E. N. 228 thereof, and,E.N.'s 6, 139, 140 of AI-An`am (VI) and E.N. 26 of Yunus (X).
*92) That is, "Now, when he has met his doom, he has nothing more to say than that he should be sent back to the world; so let him say what he likes; he will never be allowed to go back."
*93) "That is, "Now there is a `barrier' between them and the world, which will not allow them to go back to it. Therefore they shall remain in that state up to the Day of Resurrection. "
