And who is more unjust than he who prevents (men) from the masjids of Allah, that His name should be remembered in them, and strives to ruin them? (As for) these, it was not proper for them that they should have entered them except in fear; they shall meet with disgrace in this world, and they shall have great chastisement in the hereafter.

And do not make your oaths a means of deceit between you, lest a foot should slip after its stability and you should taste evil because you turned away from Allah's way and grievous punishment be your (lot).
