My impression is there is no consensus in Islam about an anthropomorphic nature of Allah. If Allah is not anthropomorphic then the meaning of monotheism must be examined more deeply.
Wikipedia says in respect to Islam: "God created...the universe governed by fixed laws that ensure the harmonious working of all things".
If the most important attribute of God is the creator of "fixed laws" or even the "fixed law" itself then most nations in history have had revealers of similar laws, most specifically moral laws.
For example, the Hebrews called the Law 'Torah', the Christians called it 'Logos' and the Buddha called it 'Niyama'.
For teachers such as the Buddha, they realized the moral law with both their internal conscience and their insight into how people morally rise & fell according to their actions (deeds).
But if you believe the One God is anthropomorphic then it will be difficult to picture how other nations came to realise the universal moral laws or One Law of religion.
If God is Law, the major religions of great nations will share a similar primary attribute. But if God is a person or ego, the major religions of great nations will be different, in conflict and engaged in breaking the Law rather than submitting to the Law.
