[Taubah 9:107] And those (hypocrites) who built a mosque to cause harm, and due to disbelief, and in order to cause divisions among the Muslims, and to await the one who is at the outset an opponent of Allah and His Noble Messenger; and they will surely swear that "We wished only good"; and Allah is witness that they are indeed liars.
[Taubah 9:108] Never stand (for worship) in that mosque *; indeed the mosque ** that has been founded on piety from the very first day deserves that you should stand in it; in it are the people who wish to thoroughly cleanse themselves; and Allah loves the clean. (*The mosque built by the hypocrites. ** The mosque at Quba, built by the Holy Prophet and his companions. The merit of praying 2 Raka’ Nawafil in it is equal to the reward of an Umrah.)
[Taubah 9:109] So is one who established his foundation upon the fear of Allah and upon His pleasure better, or the one who laid his foundation upon the brink of a falling precipice, so it fell along with him into the fire of hell? And Allah does not guide the unjust.
[Taubah 9:110] The building which they erected will constantly keep disturbing their hearts unless their hearts are torn to pieces; and Allah is All Knowing, Wise.
[Taubah 9:111] Indeed Allah has purchased from the Muslims
their lives and their wealth in exchange of Paradise for them; fighting
in Allah's cause, slaying and being slain; a true promise incumbent upon
His mercy, (mentioned) in the Taurat and the Injeel and the Qur’an; who
fulfils His promise better than Allah? Therefore rejoice upon your deal
that you have made with Him; and this is the great success.
