Hypocrites stay behind

They are miserly toward you. When fear grips them, you see them staring at you with eyes rolling in terror, like one fainting at the moment of death. But when the fear passes, they lash out at you with sharp tongues, greedy for wealth. Such people have no true faith, and that is easy for Allah

33:19Being sparing of their help to you (believers). But when the fear cometh, then thou (Muhammad) seest them regarding thee with rolling eyes like one who fainteth unto death. Then, when the fear departeth, they scald you with sharp tongues in their greed for wealth (from the spoil). Such have not believed. Therefor Allah maketh their deeds fruitless. And that is easy for Allah.
