(67) O people! if you are in doubt about the raising, then surely We created you from dust, then from a small seed, 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 stay 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 having knowledge he does not know anything; and you see the earth sterile land, but when We send down on it the water, it stirs and swells and brings forth of every kind a beautiful herbage.

(68) Whoever thinks that Allah will not assist him in this life and the hereafter, let him stretch a rope to the ceiling, then let him cut (it) off, then let him see if his struggle will take away that at which he is enraged.

(70) Then let them accomplish their needful acts of shaving and cleansing, and let them fulfil their vows and let them go round the Ancient House.
