The Qur’an clarifies the relationship between such reflection and understanding the great truths. God says:
‘They remember God when they stand, sit and lie down, and reflect on the creation of the heavens and the earth:“Our Lord, You have not created all this in vain. Limitless are You in Your glory”. (3: 191)
When they reflected, they realised that the way the heavens and the earth have been created provide clear evidence that nothing in the universe is created in vain or haphazardly.
