Quran 9:35 — Ultimatum (Bara'ah)

The day will come when their gold and silver will be heated in the fire of Hell, then used to burn their foreheads, their sides, and their backs: "This is what you hoarded for yourselves, so taste what you have hoarded."

[9:34] O you who believe, many religious leaders and preachers take the people's money illicitly, and repel from the path of GOD. Those who hoard the gold and silver, and do not spend them in the cause of GOD, promise them a painful retribution.

[9:36] The count of months, as far as GOD is concerned, is twelve.* This has been GOD's law, since the day He created the heavens and the earth. Four of them are sacred. This is the perfect religion; you shall not wrong your souls (by fighting) during the Sacred Months. However, you may declare all-out war against the idol worshipers (even during the Sacred Months), when they declare all-out war against you, and know that GOD is on the side of the righteous.
