Will the unbeliever on the Day of Resurrection not be able to argue before God that He did not cause him to die young so that he might enter Paradise like the unaccountable children?

No one has an argument against Allah Almighty; rather, Allah has the conclusive argument over all His creation. He sent messengers, revealed scriptures, removed doubts, and clarified the path. He created for humanity will and volition, by which they earn their actions. Therefore, Allah Almighty does not punish a disbeliever except for their sin.

Allah Almighty says: "Say, 'To Allah belongs the conclusive argument. If He had willed, He would have guided you all.'" This indicates His perfect wisdom in guidance and misguidance, and that had He willed, He would have guided all people.

The disbeliever has no argument against Allah. Even the inhabitants of Hell acknowledge Allah's justice and wisdom, and praise Him for His decree, as stated in His saying: "And judgment was passed between them in truth, and it was said, 'Praise be to Allah, Lord of the worlds.'" Thus, Allah Almighty is to be praised for all that He destines and decrees, and He possesses perfect wisdom and the conclusive argument over all His creation.
