“There is no compulsion for man to accept the truth. But it is certainly a shame upon the human intellect when man is not even interested in finding out as to what is the truth! Islam teaches that God has given man the faculty of reason and therefore expects man to reason things out objectively and systematically for himself. To reflect and to question and to reflect.”
“Knowing belongs to man's intellect or reason; loving belongs to his will. The object of the intellect is truth; the object of the will is goodness or love.”
“The wise men posit questions to which they may not always find immediate answers, but through their reflections God stimulates man in his search for truth - which in the last analysis is a search for God himself.”
“Man may think human intellect and reasoning are almighty, that the brain is able to comprehend all truths of the world; but the verdict of God's Word is, "vanity of vanities.”
“Man must learn to know the universe precisely as it is, or he cannot successfully find his place in it. A man should therefore use his reasoning faculty in all matters involving truth, and especially as concerning his religion. He must learn to distinguish between truth and error.”
“Do not believe a thing because you have read about it in a book. Do not believe a thing because another man has said it was true. Do not believe in words because they are hallowed by tradition. Find out the truth for yourself. Reason it out. That is realization.”
