And that He might know the hypocrites; and it was said to them: Come, fight in Allah's way, or defend yourselves. They said: If we knew fighting, we would certainly have followed you. They were on that day much nearer to unbelief than to belief. They say with their mouths what is not in their hearts, and Allah best knows what they conceal.

That is because when Allah alone was called upon, you disbelieved, and when associates were given to Him, you believed; so judgment belongs to Allah, the High, the Great.
