As He himself has said: "And your Lord is one God.
As He himself has said: "And your Lord is one God. There is no God but He, the all-merciful, the compassionate.
Surely in the creation of the heavens and the earth, and the alteration of night and day and the ship that runs in see with profit to men, and the water God sends down from heaven by which He revives the earth after its death and His scattering abroad in it all kinds of crawling creatures, and the turning about of the winds and the clouds suspended between the heaven and the earth - surely there are signs for the people of understanding. [2:163-164)" ... O' Hisham!
Almighty God has said in His book: "Surely in that there is a reminder to him who has a heart [50:37]". Heart means reason. And God has further said: "Indeed we gave Wisdom to Luqman. [31:12]" Wisdom means (the capacity of) understanding and reasoning. O' Hisham! Luqman the Sage, counseled his son: "If you bow before the Truth and the Inevitable, you will be the wisest among people, since a wise man treats himself as little before the Truth and the Inevitable. O' my son!
This world is like an unfathomable ocean in which many people have drowned. Make, therefore, the fear of God as your boat in this ocean, your faith as the main plank of the boat, the reliance of God as its sails, the reason as its rower, the knowledge as its Captain, and patience as its anchor." O' Hisham! Everything has its indicator. Man's thoughtfulness is the hall-mark of his reason. The symbol of thoughtfulness is silence.
Everything has its climax and the climax of reason is humility (before Allah's commands). It is enough to prove you are ignorant and unwise if you do what Allah has prohibited. ... O' Hisham!
Almighty God has mentioned about the people of reason in high terms, and has adorned them with the finest ornaments as per His own words: "He gives Wisdom to whomsoever He wills, and whoever is given the Wisdom, has been given much good; yet non will grasp the message but the possessors of understanding minds. [2:269]" "...
