9:34O you who believe! Many of the rabbis and priests consume people's wealth illicitly, and hinder from God’s path. Those who hoard gold and silver, and do not spend them in God’s cause, inform them of a painful punishment.

9:53Say, “Whether you spend willingly or unwillingly, it will not be accepted from you. You are evil people.”

9:54What prevents the acceptance of their contributions is nothing but the fact that they disbelieved in God and His Messenger, and that they do not approach the prayer except lazily, and that they do not spend except grudgingly.

9:92Nor on those who approach you, wishing to ride with you, and you said, “I have nothing to carry you on.” So they went away, with their eyes overflowing with tears, sorrowing for not finding the means to spend.

9:121Nor do they spend any expenditure, small or large, nor do they cross any valley, but it is recorded to their credit. That God may reward them in accordance with the best of their deeds.
