27. Except to a Messenger
(from mankind) whom He has chosen (He informs him of unseen as
much as He likes), and then He makes a band of watching guards
(angels) to march before him and behind him.
28. [He (Allâh)
protects them (the Messengers)], till He sees that they (the Messengers)
have conveyed the Messages of their Lord (Allâh). And He
(Allâh) surrounds all that which is with them, and He (Allâh)
keeps count of all things (i.e. He knows the exact number of everything).
