Hypocrites, refuse to fight

And that He might make evident those who are hypocrites. For it was said to them, "Come, fight in the way of Allāh or [at least] defend." They said, "If we had known [there would be] battle, we would have followed you." They were nearer to disbelief that day than to faith, saying with their mouths what was not in their hearts. And Allāh is most knowing of what they conceal -

Those who said about their brothers while sitting [at home], "If they had obeyed us, they would not have been killed." Say, "Then prevent death from yourselves, if you should be truthful."
