Introduction

Islam has got its own vision to the science and the knowledge which will be stated in the following:

The knowledge is of Allah which he gives to whom he wants of his servants and it is of a great value to whoever has taken it" He granteth wisdom to whom he pleaseth; and he to whom wisdom is granted receiveth indeed a benefit overflowing; but none will grasp the message but men of understanding. "(BAQARAH-269)

He real and most valuable knowledge is what about Allah which stands on the base of fearing of Allah. It is the cause to gain more of it " O ye who believe! when ye deal with each other, in transactions involving future obligations in a fixed period of time, reduce them to writing let a scribe write down faithfully as between the parties: let not the scribe refuse to write: as God h as taught him, so let him write. let him who incurs the liability dictate, but let him fear his Lord God, and not diminish aught of what he owes. if the party liable is mentally deficient, or weak, or unable himself to dictate, let his guardian dictate faithfully. and get two witnesses, out of your own men, and if there are not two men, then a man and two women, such as ye choose, for witnesses, so that if one of them errs, the other can remind her. the witnesses should not refuse when they are called on (for evidence). disdain not to reduce to writing (your contract) for a future period, whether it be small or big: it is juster in the sight of God, more suitable as evidence, and more convenient to prevent doubts among yourselves but if it be a transaction which ye carry out on the spot among yourselves, there is no blame on you if ye reduce it not to writing. but take witnesses whenever ye make a commercial contract; and let neither scribe nor witness suffer harm. if ye do (such harm), it would be wickedness in you. so fear God; for it is God that teaches you. and God is well acquainted with all things." (BAQARAH-282).
