"Perhaps that I catch up on what I wasted of the faith and the obedience." He does not have that, so he is not responded to to what he requested nor is he granted respite. For it is only a word he is saying it a word not benefiting him, and he is therein not truthful, for had he been returned to the world he would have surely returned to what he was forbidden from, and the deceased ones will remain in the barrier and the Barzakh which is between the world and the Hereafter to the Day of Resurrection and Rising.
