Such is the great emphasis in the sacred Book and in the sacred Sunnah for the believers: they should have a sound conviction and uphold all its requirements which we have enumerated. The most Exalted and the most Great One says, ‘ O believers (in the Islamic faith), believe..., ’ that is, attain your fair share of conviction so that your conduct must be up to par with it, so that you may enjoy its fruits.
Those implied in this Divine call have already attained the minimum requirement of conviction, hence they are not urged to attain it. As for others, it is something extra, perhaps a luxury, and it is not defined. There is a great deal of emphasis on the arranged order of the middle station, that is, the average individual who feels he surely believes, responding to the Divine Commandments and anything less than that.
Anything higher than that is undoubtedly closer to one’s perfection of conviction. This middle station is known to be one of the requirements. Anything less than it is not to have the same label. One must aspire to what is always higher and better. If you contemplate on this statement, you will not hesitate to roll your sleeves and exert your effort and determination to attain the handsome amount of conviction to the extent that you will be worthy of being identified with it.
Such has been the advice of Imam al-Sadiq (‘a) as narrated in Al-Kafi which cites the Imam as saying, ‘You cannot be righteous till you acquire knowledge. You cannot acquire knowledge unless you are truthful. You cannot be truthful unless you believe. These are four chapters the first of which cannot be sound without its precedent. Those who uphold only three of them stray from the right path a great deal.’ ( Al-Kafi , Vol. 2, p. 39).
Also, the Commander of the Faithful (‘a), as we are told in Al-Kafi , is quoted by Imam al-Sadiq (‘a) who cites his forefathers (‘a) quoting the Commander of the Faithful (‘a) saying, ‘Conviction ( iman ) stands on four corners: reliance on Allah, surrender to His will, acceptance of His destiny, and yielding to the Commandment of Allah, the most Exalted, the most Great.’ ( Al-Kafi , Vol. 2, p. 47).
