The architect made an effort on paper and he got a plan of a skyscraper on paper. The builder made an effort on sand and he got a building standing up on sand. The engineer made effort on metal and he got an airplane flying in the air. The doctor made an effort on medicine and he has managed to enter the human body with all his instruments. Nevertheless, after all their efforts and achievements, if they failed to recognise their creator, then none of them are intelligent. On the other hand if we have a simple farmer who does not know how to read, write or count. All he knows is that the rain comes down and his crops grow up and in the system of the rain coming down and the crops going up, he recognises Allah Ta’ala, then this farmer is intelligent. Because the yardstick of intelligence is the recognition of Allah Ta’ala, and not the accomplishments of this material world.
