بِسۡمِ ٱللهِ ٱلرَّحۡمَـٰنِ ٱلرَّحِيمِ
ِIn the Name of Allah Most-Compassionate, Most-Merciful
Everyone destination and level of knowledge is different. The guidance of Allah is unique, whoever is guided will be uniquely guided.
Yet, verily, it is not their eyes that have become blind –
but blind have become the hearts that are in their chests!”
Those who are blind internally, while they can see with the external eyes, they understand everything externally in it's outward physical form.
Here are a few examples from the holy Quran about the knowledge
0 Adam! Dwell you and your wife in the Paradise and eat both of you freely with pleasure and delight of things therein as wherever you will, but come not near this tree or you both will be of the Zalimeen (wrong-doers). " Surah 2: 35
Knowledge is like a fruit, do not learn or take their knowledge or you will be of the wrong-doers.
Allah further mentionned in the Quran concerning the word "Tree"
Seest thou not how Allah sets forth a parable? – A goodly word like a goodly tree, whose root is firmly fixed, and its branches (reach) to the heavens,- of its Lord. So Allah sets forth parables for men, in order that they may receive admonition. It brings forth its fruit at all times, by the leave of its Lord. So Allah sets forth parables for men, in order that they may receive admonition. And the parable of an evil Word is that of an evil tree: It is torn up by the root from the surface of the earth: it has no stability. Allah will establish in strength those who believe, with the word that stands firm, in this world and in the Hereafter; but Allah will leave, to stray, those who do wrong: Allah doeth what He willeth. (Ibrahim 14:24-27)
Ta’weel (The true reality of things, and what they will turn out to be)
“[He said], “Yusuf, O man of truth, explain to us about seven fat cows eaten by seven [that were] lean, and seven green spikes [of grain] and others [that were] dry – that I may return to the people; perhaps they will know.”
“[Yusuf] said, “You will plant for seven years consecutively; and what you harvest leave in its spikes, except a little from which you will eat.” And Verse 48 says:
Then will come after that seven difficult [years] which will consume what you saved for them, except a little from which you will store. And Verse 49 says:
“Then will come after that a year in which the people will be given rain and in which they will press [olives and grapes].”
