9:38O you who believe! What is the matter with you, when it is said to you, “Mobilize in the cause of God,” you cling heavily to the earth? Do you prefer the present life to the Hereafter? The enjoyment of the present life, compared to the Hereafter, is only a little.

9:39Unless you mobilize, He will punish you most painfully, and will replace you with another people, and you will not harm Him at all. God has power over all things.

9:41Mobilize, light or heavy, and strive with your possessions and your lives in the cause of God. That is better for you, if you only knew.

9:46Had they wanted to mobilize, they would have made preparations for it; but God disliked their participation, so he held them back, and it was said, “Stay behind with those who stay behind.”

9:47Had they mobilized with you, they would have added only to your difficulties, and they would have spread rumors in your midst, trying to sow discord among you. Some of you are avid listeners to them. God is Aware of the wrongdoers.
