Man's Haste and Prayers against Himself

Allah tells us about man's haste and how he sometimes prays against himself or his children or his wealth, praying for something bad to happen for them, or for them to die or be destroyed, invoking curses, etc. If Allah were to answer his prayer, he would be destroyed because of it, as Allah says:

وَلَوْ يُعَجِّلُ اللَّهُ لِلنَّاسِ الشَّرَّ

Perhaps, it is based on this congruity that it was said in verse 11 that man would, on occasions, pray for something in a haste, something that spells out destruction for him. If Allah Ta` ala were to answer such a prayer, he would be ruined. But, Allah Ta’ ala does not answer such prayers instantly until man himself comes to realize that his prayer was made in error and that it was fatal for him. Then, in the last sentence of this very verse, a natural weakness of man has been mentioned in the form of a standing rule - that man is, by nature, haste-prone. He keeps his sight trained on passing profit and loss and falls short on foresight and hindsight. He loves to go for the immediate gain and comfort, even if it happens to be only a little. He would not bat an eye to prefer it to the greater and more lasting gain and comfort. In short, this verse points out to a natural weakness of human beings in general.
