Those who do not know say, "Why does Allāh not speak to us or there come to us a sign?" Thus spoke those before them like their words. Their hearts resemble each other. We have shown clearly the signs to a people who are certain [in faith].
Those without knowledge from among the People of the Scripture and the idolaters asked, in their stubbornness against the truth, why Allah did not speak to them directly, or why a miracle was not sent for them to see. Disbelieving communities said similar things to their prophets in the past: their hearts are all similar, because all disbelievers are the same, even if they are from different times and places. Allah makes His signs clear to those who are certain of the truth when it appears to them, not doubting or resisting it.
