If two or more gods created an existent...
If two or more gods created an existent, it would imply that each of the assumed gods would create an existent. This would result in many existents, whereas in reality there is only one. If it is to be assumed that a particular god creates each particular phenomenon, this will imply that each phenomenon exists because of its particular god. Furthermore they must not require or depend upon any other existent unless the (dependency) need returns to their particular god.
This type of requirement or need must be upon the existent, which is created by that very creator who has created that particular group. In other words, the assumption of having more than one god necessitates the order in the universe to be multifarious and deteriorating. In reality there is only one order and all phenomena are related and effectual upon each other and at the same time need each other.
Furthermore the present phenomenon is linked with the former phenomenon and every coexisting phenomenon creates grounds for future phenomena. Hence a universe, which is linked and related to each other (interwoven with each other) is governed under a sole order and it (this universe) cannot be an effect of several causes that bestow existence.
Moreover, if the assumption is made that the creator of the creation is one, and other gods are the administrators and governors of the universe, this is also incorrect, because every effect with all its being is established on the cause that bestows existence (‘illah mufīda lil-wujūd). No independent existent has the means to interfere unless the results and outcomes of effects of a cause are all under the authority of the existence-bestowing agent and take place with the will of the Divine.
In this case none of them would be considered as lord because the true meaning of ‘lord’ means the one who can freely and independently intervene in the creation. However there is no intervention, but in the dissipation of the lordship given by the Creator and with the power He has bestowed. This form of executing does not contradict with the oneness of lordship because the oneness of creatorship, does not contradict ‘the creating’ with the Divine decree of the Creator.
In the Noble Qur’an and traditions we find a similar type of creation or origination based on Allah’s support and godly power.
