He also knows (the rich that are niggardly) who taunt the believers that voluntarily give alms, they scoff at those who have nothing to give except what they earn through their hard toil. Allah scoffs at them in return. A grievous chastisement awaits them.
信士中有人慷慨捐献，有人（因为贫穷）只能出力，对于嘲笑他们的伪信者，真主将以嘲笑的刑罚报答他们。
