(People like prophet Solomon ( ‘a ) had such a state that they used to eat dry bread in spite of having so much wealth and a great kingdom and lived in contentment and frugality.) In explanation of the sentence, “Allah stabilizes wisdom in his heart” it is necessary to mention a few points: There is a close relationship between disinclination to the world and perception of divine knowledge; that is to say, it is impossible to find a person who in spite of his heart being obsessed with the world, his soul at the same time is overflowing with divine knowledge and awareness.
Wisdom, which is a product of disinclination to the world, stabilizes man’s knowledge and awareness and defends against instability of belief and wavering of the mind. It is possible for man to attain knowledge and perceive the truth but still his awareness is shaky and unstable because he has not attained certitude or certainty, which stabilizes and steadies knowledge in the heart.
They associate others (with Him).” [^2] Once wisdom has become steady, it does not remain confined to the heart but its effects become apparent in speech and works and conduct too. The words of a person in whose heart wisdom has become stable will also be wise: he abstains from vain and futile talk and counsels in such a philosophical and thoughtful way that his words deserve praise and extolment.
Yes, the tongue is passage for man’s heart and, in other words, the exudations of a man’s heart are carried out on the tongue because it is the oozing external part of the jar which is inside him, of course this oozing out not only appears on the tongue but with the rest of man’s conduct too.
