in Edition Clear Qur'an by Talal Itani / An-Nisaa (The Women)

4:75And why would you not fight in the cause of God, and the helpless men, and women, and children, cry out, “Our Lord, deliver us from this town whose people are oppressive, and appoint for us from Your Presence a Protector, and appoint for us from Your Presence a Victor.”

4:77Have you not considered those who were told, “Restrain your hands, and perform your prayers, and spend in regular charity”? But when fighting was ordained for them, a faction of them feared the people as God is ought to be feared, or even more. And they said, “Our Lord, why did You ordain fighting for us? If only You would postpone it for us for a short while.” Say, “The enjoyments of this life are brief, but the Hereafter is better for the righteous, and you will not be wronged one bit.”
