He reveals this to none, 26 Except to him whom He chooses as an apostle; for surely He makes a guard to march before him and after 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
