Quran 6: 65, which means:
(Say: He is All-Able to send forth upon you, [associaters,]
chastisement from above you b
or from under your feet c
, or to confuse you into sects d and to make you suffer of the violence of one another e .
Behold [Mohammed] how We turn about the revelations f ; haply that they may understand. g)
65 b Like thunderbolts, meteors, meteorites, comets, hurricanes, heat and coldness so that He may destroy you with one of these factors.
65 c Like the cleavage, earthquake, volcano, drowning with sea water and microbes which are on the surface of the earth, so that He may destroy you with anyone of them.
65 d i.e. Or He may confound you, and you then become many sects, i.e. divisions and parties opposing each other, and so the enmity will be inserted among you.
65 e Which is the war and fighting that will occur among you because of the enmity.
65 f i.e. We explain and repeat [in many ways] the revelations as parables, admonition, and warning.
65 g i.e. so that they may realize the truth, and they may be relieved from their doubt and suspicion.
