And so that He knows the hypocrites whom Allah exposed what was in their hearts when the believers said to them: "Come fight with us in the cause of Allah, or be a help for us by your increasing our numbers," so they said: "If we knew that you were fighting someone we would surely have been with you against them," they are to disbelief on this day closer than they are to faith; because they say with their mouths what is not in their hearts. And Allah is more knowing of what they hide in their chests.
