"O people, keep your duty to your Lord; surely the shock of the Hour is a grievous thing. The day you see it, every woman giving suck will forget her suckling and every pregnant one will lay down her burden, and thou wilt see men as drunken, yet they will not be drunken, but the chastisement of Allah will be severe. And among men is he who disputes about Allah without knowledge, and follows every rebellious devil -- For him it is written that whoever takes him for a friend, he will lead him astray and conduct him to the chastisement of the burning Fire. O people, if you are in doubt about the Resurrection, then surely We created you from dust, then from a small life-germ, then from a clot, then from a lump of flesh, complete in make and incomplete, that We may make clear to you. And We cause what We please to remain in the wombs till an appointed time, then We bring you forth as babies, then that you may attain your maturity. And of you is he who is caused to die, and of you is he who is brought back to the worst part of life, so that after knowledge he knows nothing. And thou seest the earth barren, but when We send down thereon water, it stirs and swells and brings forth a beautiful (growth) of every kind."
