Al-Ahzab 33:19 اشحة عليكم فاذا جاء الخوف رايتهم ينظرون اليك تدور اعينهم كالذي يغشى عليه من الموت فاذا ذهب الخوف سلقوكم بالسنة حداد اشحة على الخير اولايك لم يومنوا فاحبط الله اعمالهم وكان ذالك على الله يسيرا ١٩

(and that too) with a greed against you (i.e. to extract a share of spoils from you). But when fear comes, you will see them looking towards you, rolling their eyes, like the one who gets faint because of death. Then once fear is gone, they assail you with sharp tongues, in greed for the good (i.e. the wealth acquired as spoils). These people did not accept faith (in real terms), therefore Allah has nullified their acts. All this is so easy for Allah.
