“Faith in God comes of a light that God casts into the hearts of His servants, as a gift and a gratuity from Him. True faith (al-iman al-rasikh) is the faith of the masses that develops in their hearts from childhood due to their constant exposure (to religious material), or that accrues to them after they have reached the age of majority as a result of experiences that they cannot fully articulate.’ “
–the difference between being informed and coming to a realization might be likened to the difference between hearing the words, “I love you,” after one and after forty years of marriage.
…speaks of the means via which one comes to realize the truth of the prophethood of Muhammad (salallahu alayhi wasalam). It is by experiencing, in other words, the truth of such Prophetic teachings as, ‘Whoever acts on the basis of what they know, Allah will grant them knowledge of what they do not know,’ or ‘Whoever assists an evil-doer (zalim), Allah will eventually turn the latter against them,’ that one comes to realize the truth of the Prophet’s message.
“this is the means by which you should seek certainty of (a claim to) prophethood, not by (a person’s) turning a staff into a snake or splitting the moon. For when you observe the latter alone without the benefit of extraneous corroborative indicators too numerous to count, you may think that you are observing a feat of magic or a phantasm or that this is simply a test from God via which He intends to lead people astray. For, indeed, ‘He leads astray whomever He wills and He guides whomever He wills.’” —Munqidh
