And the Hypocrites also. These were told: "Come, fight in the way of God, or (at least) drive (The foe from your city)." They said: "Had we known how to fight, we should certainly have followed you."

They swear by God that they said nothing (evil), but indeed they uttered blasphemy, and they did it after accepting Islam; and they meditated a plot which they were unable to carry out: this revenge of theirs was (their) only return for the bounty with which God and His Apostle had enriched them! If they repent, it will be best for them; but if they turn back (to their evil ways), God will punish them with a grievous penalty in this life and in the Hereafter: They shall have none on earth to protect or help them.
