2:83We made a covenant with the Children of Israel: “Worship none but God; and be good to parents, and relatives, and orphans, and the needy; and speak nicely to people; and pray regularly, and give alms.” Then you turned away, except for a few of you, recanting.

2:118Those who do not know say, “If only God would speak to us, or a sign would come to us.” Thus said those who were before them. Their hearts are alike. We have made the signs clear for people who are certain.

2:174Those who conceal what God revealed in the Book, and exchange it for a small price—those swallow nothing but fire into their bellies. And God will not speak to them on the Day of Resurrection, nor will He purify them, and they will have a painful punishment.
