48:15Those who lagged behind will say when you depart to collect the gains, “Let us follow you.” They want to change the Word of God. Say, “You will not follow us; God has said so before.” Then they will say, “But you are jealous of us.” In fact, they understand only a little.

48:16Say to the Desert-Arabs who lagged behind, “You will be called against a people of great might; you will fight them, unless they submit. If you obey, God will give you a fine reward. But if you turn away, as you turned away before, He will punish you with a painful punishment.”
