So We will surely ask those to whom messengers were sent. The phrase 'sent to them' is connected to the preposition 'to them'. Its meaning is: So We will ask the ones sent to, who are the nations, about what they responded to their messengers. As He said: 'And on the Day He will call them, and He will say, What did you answer the messengers?' And He will ask the messengers about what they were answered with, as He said: 'On the Day Allah gathers the messengers and He will say, What were you answered?' So We will surely recount to them, concerning the messengers and those to whom they were sent, what was from them, with knowledge of their apparent and hidden conditions, and their words and actions, and what we were not absent from regarding them and what was found from them. If you say: If He is All-Knowing of that and is recounting it to them, what is the meaning of asking them? I say its meaning is reproach, reprimand, and confirmation when they speak it with their tongues and their prophets bear witness against them.
