For every age there is a law. 38 Allah effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance. 39 Whether We let thee see something of that which We have promised them, or make thee die (before its happening), thine is but conveyance (of the message).

Say: 'God suffices as a witness between me and you, and whosoever possesses knowledge of the Book.' 43
