"Behold! In the creation of the heavens and the earth, and the alternation of Night and Day,- there are indded Signs for men of understanding."

[The Holy Qur'an Surah Imran, Chapter 3 and Verse 190]

From the view point of practice, the Holy Quran awakened the dormant reason of man by declaring that he should not stand in awe of the heaven and the earth or the night and day. They have been created for man's good; he has not been created for them. Therefore, it is the duty of mankind to study the alternation of the night abd the day and the creation of the heavens and the earth and to subjugate the universe. Thus it will find an endless treasures of knowledge and power; it will discover innumerable proofs of Divine Unity and it will gain conviction of the wisdom, power and sovereignty of God. This verse teaches us that the promotion of scentific knowledge is one of the objects of the Quran. Therefore, it os the duty of the Muslims to acquire expert knowledge of the science.
