Quran 9:107 — Ultimatum (Bara'ah)

There are those who abuse the masjid by practicing idol worship, dividing the believers, and providing comfort to those who oppose GOD and His messenger. They solemnly swear: "Our intentions are honorable!" GOD bears witness that they are liars.

[9:106] Others are waiting for GOD's decision; He may punish them, or He may redeem them. GOD is Omniscient, Most Wise.

[9:108] You shall never pray in such a masjid. A masjid that is established on the basis of righteousness from the first day is more worthy of your praying therein. In it, there are people who love to be purified. GOD loves those who purify themselves.
