And the mothers should suckle their children for two whole years for him who desires to make complete the time of suckling; and their maintenance and their clothing must be-- borne by the father according to usage; no soul shall have imposed upon it a duty but to the extent of its capacity; neither shall a mother be made to suffer harm on account of her child, nor a father on account of his child, and a similar duty (devolves) on the (father's) heir, but if both desire weaning by mutual consent and counsel, there is no blame on them, and if you wish to engage a wet-nurse for your children, there is no blame on you so long as you pay what you promised for according to usage; and be careful of (your duty to) Allah and know that Allah sees what you do.

Or the like of him (Uzair) who passed by a town, and it had fallen down upon its roofs; he said: When will Allah give it life after its death? So Allah caused him to die for a hundred years, then raised him to life. He said: How long have you tarried? He said: I have tarried a day, or a part of a day. Said He: Nay! you have tarried a hundred years; then look at your food and drink-- years have not passed over it; and look at your ass; and that We may make you a sign to men, and look at the bones, how We set them together, then clothed them with flesh; so when it became clear to him, he said: I know that Allah has power over all things.
