All living and even non-living beings are in continuous need of many things even a small portion of which they are unable to supply by themselves. For example the operation and maintenance of the universe demand the existence of certain universal laws such as growth reproduction gravitation and repulsion.

However these laws which we call 'natural laws' have no external visible or material existence; they exist nominally. Something with a nominal existence only which has no knowledge and consciousness can evidently not be responsible for a miraculous creation which requires absolute power and absolute knowledge wisdom and power of choice and preference. So one who has all these attributes has established these 'natural laws' and uses them as veils before His operations for a certain purpose.

Also plants need air water heat and light for their life none of which they are able to meet by themselves. As for the needs of man they are too many to enumerate. Fortunately all his essential needs from the very beginning of his earthly existence in his mother's womb to his death are met beyond his own capacity and intervention. When he enters into the world he finds everything prepared to meet all the needs of his senses and intellectual and spiritual faculties. This clearly shows that one who is infinitely merciful and knowledgeable provides for all created beings in the most extraordinary way and causes all things to collaborate to that end.
