The second guidance is by the Qur'an...
The second guidance is by the Qur'an; therefore, the first one must have been before the Qur'an. They must have been guided by a healthy and unimpaired psychology. If a man's nature is faultless and flawless, it cannot fail to see that it is dependent on something above it. Also, it realizes that every other thing, which it may perceive, imagine or understand, depends likewise or, a thing outside the chain of dependent and needy things.
Thus, it comes to believe that there must be a Being, unseen and imperceptible through the senses, who is the beginning and end of every other thing. It also sees that the said Essential Being does not neglect even the smallest detail when it comes to creative perfection of His creatures. This makes him realize that the said Creator cannot leave the man to wander aimlessly hither and thither in his life; that He must have provided for him a guidance to lead him aright in his actions and morals.
By this healthy reasoning, the man acquires the belief in One God, in the institution of prophethood and in the Day of Resurrection. In this way, his faith in the fundamentals of religion becomes complete. That faith leads him to show his servitude before his Lord, and to use all that is in his power - wealth, prestige, knowledge, power, and any other excellence - to keep this faith alive and to convey it to others. Thus we come to the prayer and benevolent spending.
The five virtues enumerated in these verses are such that a healthy nature unfailingly leads the man to them. Once a man reaches this stage, Allah bestows on him His other grace, that is, the guidance by the Qur'an. The above-mentioned five qualities - correct belief and correct deeds - fall between two guidances, a preceding one and a following one. This second guidance is based on the first one.
This fact has been described in the following verses : Allah confirms those who believe with the sure word in this world's life and in the hereafter (14:27). O you who believe! fear Allah and believe in His apostle. He will give you two portions of His mercy, and make for you a light with which you will walk . . . (57:28). O you who believe! if you help Allah, He will help you and make firm your feet (47:7). And Allah does not guide the unjust people (61:7) . . . .
and Allah does not guide the transgressing people (61:5). The same is the case with error and straying of the disbelievers and hypocrites, as will be seen later on.
