They said: "Do not fear, for indeed We have come with the punishment which your people used to doubt therein and not confirm, and We have come to you with the truth from with Allah, and indeed We are surely truthful, so go out from among them and with you your believing family, after the passing of a portion of the night, and walk you behind them; lest any one of them stays behind thus the punishment strikes him, and beware that any of you looks back, and hasten to where Allah commanded you; so that you be in a secure place."
