Those who are listening intently to the Word and they are following the best of it, those are they whom Allah Guided, and those, they are the ones of understanding [39:18] .
Luqman -as said to his -as son: ‘Be humble to the Truth, you will come to be the most intellectual of the people, and that the attractiveness in front of the Truth is of little (value). O my -as son! The world is a deep ocean.
A lot of learned people have drowned in it, therefore make your ship in it to be the fear of Allah -azwj , and the Eman to be its load, and the reliance (upon Allah -azwj ) as its sails, and the intellect as its captain, and the knowledge as its indicator (navigator), and the patience as its passenger’.
It was so that Amir Al-Momineen -asws was saying: ‘Allah -azwj has not been worshipped with anything superior than the intellect’.
And the intellect of a person cannot be completed until there happen to be various characteristics in him – The (people would be) secured from (any form of) disbelief and the evil (being exercised) from him, and both the righteous guidance and the goodness be expected from him; he would give away from the excess of his wealth, and he would restrain from the excess of his words, and his share from the world would (just) be the subsistence (an extract) [7] Therefore, making an effort to understand Islam through ‘aql’ (intellect) is expected from the devout servants of Allah -azwj .
However, simple beliefs and acts of worship were subjected to gradual changes, either deliberately or due to forgetfulness of the Hadith narrators/compilers.
