He who disobeys Allah and His Messenger, for him is the Fire of Gehenna, which he will be in for ever. 23 When they see that which they were promised they shall know who is weaker in helpers and fewer in numbers. 24 Say: 'I do not know whether that which you are promised is near, or whether my Lord will set for it a time. 25 [He is] Knower of the unseen, and He does not disclose His [knowledge of the] unseen to anyone 26 other than to a Messenger whom He chooses (for the bestowal of any part of the knowledge of the Unseen), whereafter He appoints guards who go before him and behind him, 27 so as to make manifest that it is indeed [but] their Sustainer's messages that these [apostles] deliver: for it is He who encompasses [with His knowledge] all that they have [to say,] just as He takes count, one by one, of everything [that exists]. 28
