And those who rooted firmly in knowledge say: We believe in it; all is from our Lord; yet none remembers, but the men who possess minds. [3:7]" "What? Is he who knows what has been sent down to you from your Lord is the truth, like him who is blind (void of knowledge)? Only the possessors of understanding minds will remember. [13:19]" "(O' Muhammad!) A book We have sent down to you, blessed, that the people of understanding may ponder its signs and so remember.

[38:29]" Shi'ite reference: Usul al-Kafi, Chapter of "Reason and Ignorance", a part of Tradition #12 (Part IV) Tradition #12 continued: Imam Musa al-Kazim (AS) added: O' Hisham! God has appointed His prophets and messengers to make people wise and mindful of God. The more they accept and believe in these messengers, the greater is their God-consciousness. The wisest among men is he who knows about Allah most.

He who is the most perfect in his reasoning enjoys the highest status among people in this life and the life of hereafter. O' Hisham! God has given two proofs for the guidance of mankind - the explicit/external, and the implicit/internal. The explicit/external proof is in the form of prophets, messengers, and the Imams (divinely- appointed guides). And the implicit/internal proof is in the form of reasoning and understanding. O' Hisham!

A man of reason does not let his lawful occupations prevent him from thanksgiving/service to Allah, nor does the attraction of unlawful acts wear out his patient. O' Hisham! One who allows three things to be dominated by another set of three things, has actually destroyed his reason. The first thing is to allow the reason to be dominated by excessive hopes and expectations. The second thing is to allow the highest of wisdom to be dominated by excessive utterances.

The third thing is to allow his admonition light to be extinguished/dominated by carnal desires. And the one who destroys his reason (by doing the above three) also destroys both his worldly life and his faith. ... O' Hisham! Truth is a sign of obeying God (i.e., truth leads to obey God). And there is NO salvation except through obedience to God. Obedience to Him can only be performed by means of knowledge.

And knowledge is a matter of acquisition, and this acquisition is only through reason and intellect. And there can be NO knowledge except through the learned in divinity (`Aalimun Rabbani). And the consciousness of knowledge is through reason and intellect. O' Hisham!
