Knowledge (3ilm) and Understanding (Fiqh)

Have you not considered how Allah presents an example, [making] a good word like a good tree, whose root is firmly fixed and its branches [high] in the sky?

It produces its fruit all the time, by permission of its Lord. And Allah presents examples for the people that perhaps they will be reminded.

And the example of a bad word is like a bad tree, uprooted from the surface of the earth, not having any stability. [14:24-26]

The following are from Jesus (a.s.) taken from the Gospel of Matthew - and it is extracts of his teachings to the disciples on the nature of Knowledge in humans. 

The double-edged sword (dangers and virtues) of humanities innate ability to "grow" new knowledge (via logical links and manipulation, insight, creativity, etc)

Some people claim that the safest way is to simply accept knowledge as it comes and pass it on, without adding anything of our own understanding to it.  This is something angels would do but it is not in our human nature.  To do this would be safer, but it would also deny our innate human nature which God has created us with and from it made us superior to the angels.  Just because something carries negatives, does not mean we should completely abandon that "gift".  To do so may leave us without a "gift" and still a lot of negatives!!!

The Parable of the Sower  (Knowledge/3ilm vs Understanding/Fiqh)

³ Then he told them many things in parables, saying: “A farmer went out to sow his seed. ⁴ As he was scattering the seed, some fell along the path, and the birds came and ate it up. (¹⁹ When anyone hears the message about the kingdom and does not understand it, the evil one comes and snatches away what was sown in their heart. This is the seed sown along the path.)

⁵ Some fell on rocky places, where it did not have much soil. It sprang up quickly, because the soil was shallow. ⁶ But when the sun came up, the plants were scorched, and they withered because they had no root. (²⁰ The seed falling on rocky ground refers to someone who hears the word and at once receives it with joy. ²¹ But since they have no root (yaqeen - surety - firm belief of the message, principles, experience, etc), they last only a short time. When trouble or persecution comes because of the word, they quickly fall away. )

⁷ Other seed fell among thorns, which grew up and choked the plants. (²² The seed falling among the thorns refers to someone who hears the word, but the worries of this life and the deceitfulness of wealth choke the word, making it unfruitful.)

⁸ Still other seed fell on good soil, where it produced a crop—a hundred, sixty or thirty times what was sown.  (²³ But the seed falling on good soil refers to someone who hears the word and understands it. This is the one who produces a crop, yielding a hundred, sixty or thirty times what was sown.”)

The Parable of the Weeds (dangers of interpreting knowledge)

²⁴ Jesus told them another parable:

“The kingdom of heaven is like a man who sowed good seed in his field (Truthful message from God's books and messengers). ²⁵ But while everyone was sleeping, his enemy (the enemy who sows them is the devil) came and sowed weeds (The weeds are the people of the evil one) among the wheat (good people), and went away ²⁶ When the wheat sprouted and formed heads, then the weeds also appeared.

²⁷ “The owner’s servants came to him and said, ‘Sir, didn’t you sow good seed in your field? Where then did the weeds come from?’ ²⁸ “‘An enemy did this,’ he replied.

“The servants asked him, ‘Do you want us to go and pull them up?’ (kill the evil ones?)
²⁹ “‘No,’ he answered, ‘because while you are pulling the weeds, you may uproot the wheat with them. (as you kill the evil ones you may kill good people by mistake)

³⁰ Let both grow together until the harvest (The harvest is the end of the age - let God sort them on the day of Judgement - just focus on being the wheat). At that time I will tell the harvesters (the harvesters are angels): First collect the weeds and tie them in bundles to be burned (As the weeds are pulled up and burned in the fire, so it will be at the end of the age.); then gather the wheat and bring it into my barn. (Paradise) ’"

Muhammad is the Messenger of Allah ; and those with him are forceful against the disbelievers, merciful among themselves. You see them bowing and prostrating [in prayer], seeking bounty from Allah and [His] pleasure. Their mark is on their faces from the trace of prostration. That is their description in the Torah. And their description in the Gospel is as a plant which produces its offshoots and strengthens them so they grow firm and stand upon their stalks, delighting the sowers - so that Allah may enrage by them the disbelievers. Allah has promised those who believe and do righteous deeds among them forgiveness and a great reward. [48:29]
