If you have received an outer injury (in the Battle of Uhud), surely, the (disbelieving) people have already received a similar injury (in the same battle) - these days of vicissitudes are those which We cause to alternate among the people, (it is so that you may be admonished) and that (among other things), Allâh may distinguish those who (really) believe and so that He may raise martyrs from among you; and Allâh does not love the unjust.
