For every term there is a Book: for every time there is an affair that is prescribed and predetermined or ordained in that moment for creatures. Subsequently, divine precepts are designated by God in accordance with [specific] moments. For every moment there comes from Him a messenger bearing what is good for that [particular] time. Likewise is the case with all things that originate in time, such as signs and otherwise; and it was not for any messenger to bring, anything of the sort except by His leave and at the [appointed] time, since these [signs] are designated [certain] times at which they come into existence without being changed, substituted, brought forward or delayed.
