Those who were left behind were glad on account of their sitting behind Allah's Messenger and they were averse from striving m Allah's way with their property and their persons, and said: Do not go forth in the heat. Say: The fire of hell is much severe in heat. Would that they understood (it).

(Firon) said: You believe in him before I give you leave; most surely he is the chief of you who taught you enchantment, therefore I will certainly cut off your hands and your feet on opposite sides, and I will certainly crucify you on the trunks of the palm trees, and certainly you will come to know which of us is the more severe and the more abiding in chastising.

Say to those of the dwellers of the desert who were left behind: You shall soon be invited (to fight) against a people possessing mighty prowess; you will fight against them until they submit; then if you obey, Allah will grant you a good reward; and if you turn back as you turned back before, He will punish you with a painful punishment.
