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 -

when it was said to them, ‘Come, fight for God’s cause, or at least defend yourselves,’ answered, ‘We would follow you if we knew there was going to be fighting.’ On that day they were closer to disbelief than belief. They say with their tongues what is not in their hearts: God knows exactly what they conceal.

And that He might test the hypocrites, it was said to them: "Come, fight in the Way of Allâh or (at least) defend yourselves." They said: "Had we known that fighting will take place, we would certainly have followed you." They were that day, nearer to disbelief than to Faith, saying with their mouths what was not in their hearts. And Allâh has full knowledge of what they conceal.
