"SPIRIT" AND "PROPHET" SYNONYMOUS
(holy bible) john 16:13
it has already been established that. biblically, the word "spirit" is used synonymously for "prophet," by the same author in 1 john 4: 1 (as seen earlier).
hence the "spirit of truth" would be the prophet of truth. a prophet in whom truth is personified. he had walked through life so honourably and industriously that he had won for himself even from his pagan fellow countrymen the noble designation of as-saadiq (the truthful one) and al-amin, "the honest," "the upright." "the trustworthy;" the man of faith who never broke his word. his life, his personality, his teachings are the veritable proof of muhummed (pbuh) being the embodiment of truth (al-amin) — the spirit of truth!
