Indisposed1 toward you. And when fear comes, you see them looking at you, their eyes revolving like one being overcome by death. But when fear departs, they lash you with sharp tongues, indisposed toward [any] good. Those have not believed, so Allāh has rendered their deeds worthless, and ever is that, for Allāh, easy.
Translation: Saheeh International (English)
1 Literally, "stingy," i.e., unwilling to offer any help.
O group of believers, they are miserly with you with their wealth, so they do not help you by spending it; miserly with their souls, so they do not fight alongside you; and miserly with their love, so they do not love you. Then when fear at the time of meeting the enemy comes, you will see them looking at you, O Messenger, with their eyes rolling out of cowardice, just as the eyes of a person who is suffering the pangs of death roll. But when fear leaves them and they become content, they harm you verbally with abusive sharp tongues. They are greedy for booty which they look for. Those who have been described with these qualities have not truly believed, so Allah cancelled the reward of their actions. And this cancelling was easy for Allah.
