Allahu Ta'âlâ Is The Creator Of Everything

Hadrat Imâm-i Rabbânî says in the 17th letter of the third volume of his Maktûbât:

As human beings are creatures, so all their deeds and actions are Allahu ta'âlâ's creatures. For, nobody besides Him can make or create anything. How can a creature create another, while it itself has been created? The stamp of createdness denotes little power and signifies insufficient knowledge. He who has little knowledge and power cannot create or invent.

In man's action, what falls to his lot is a result of his acquiring. That is, action has been produced through his power and will. It is Allahu ta'âlâ who has created and made that action. It is man who has acquired it. As it is seen, the optional actions of men, those which they do willingly, happen from their acquiring and Allah's creating. If man's acquiring or option [that is, his liking] does not take part in his action, that action turns into convulsions. [It becomes like the movement of the stomach or of the heart.] However, it is obvious that optional actions are not like them. The difference between optional actions and convulsions, though they are both created by Allahu ta'âlâ, is in the acquiring.

Pitying His born servants, Allahu ta'âlâ made the creation of their actions dependent upon their intention and wish. He creates man's action when man wants. It is for this reason that man is responsible. The blessing or the sin of the action is given to man. The intention, the option, which Allahu ta'âlâ has given to His born servants, is equal in doing or not doing the action. He declared clearly to His born servants through His prophets which actions are good or bad to do or not to do. Man, being free to do or not to do each of his actions, will for certain choose one of them; the action will be either good or bad, and he will receive either a blessing or a sin.
