Muslims submit only to Allah, the Creator of all, without association or partnership, and without contradicting the natural rules of the circumstantial placement of all creations. Believers find in all creations, the sign of the unity of Allah, whether they are men or not. Thus, submission to the design and pattern of the livelihood of all things is witnessed not only among men, but even with birds, that we do not normally speak to, nor are specifically given the option to answer the call to the way of Allah by His Messenger(s). The Qur’an says:

Seeth thou not that to Allah bow down in worship all things that are in the heavens and on earth; the sun, the moon, the stars; the hills, the trees, the animals; and a great number among Mankind? But a great number are (also) such as are fit for punishment: and such as Allah shall disgrace, none can raise to honour: for Allah carries out all that He wills.
Qur’an 22:18
