Here in the above verses, the reference is to the Holy Qur'an which guides man to a way which is the most upright to prosperity. The way through which Qur'an leads man to his Merciful Lord, and originator in creation is very straight, plain, evident, the shortest, and very reasonable, Qur'an's social and political programs cover all aspects of Man's physical and spiritual life, by being moderate and avoiding the extremes, its instruction and laws are everlasting and the best, because it is the last and seal of the Divine Books.

The next verse(NO.11) implies that Man is very hasty by nature. He is usually impatient and has quick temper, while patience in the religion, is similar in position to the head in a body, in this respect Shakespeare has a beautiful verse, saying: -

How poor are they that have no patience!

What wound did ever heal, but by degree.

Then let us not be so hasty as to pray for evil as pray for good, we better rejoice in what has been given us and be not so hasty about things which Allah in His wisdom and Universal Plan, has thought it better to withhold from us. HAZRAT IMAM SADIQ has said: -

Know the way to your rescue and peril, lest you ask God for something that will bring you destruction; while you may think that your rescue is in it. This is because Allah has said in His Book; Man prays for evil as he prays for good, and he is hasty.

The next verse (NO.12) refers to the importance of Day and Night, as two different signs of God's Grace and Mercy. Darkness and light; shadow and sunshine are both, very important signs of God, that alternately one appears when the other disappears. Night and Day are both gifts of God; one for rest and repose, and the other for work and study. The regular sun rise and sun set gives us the possibility of reckoning the week, month and year;-

And we have made the night and day as two signs… so that you may seek Grace from your Lord, and to know the number of the years and reckoning.
