Hey Ibrahim
I think I understand you, but this information is far more about muslim theology than I would be familiar with.
On your comment,
Of course some Copts and Arab Christians adopted the same concept ... but without a Christian theological basis
I don't get that at all, what people adopted is just a habit in naming their kids, not a polytheitic concept.
There is no contradiction between having one, say, president, but describing him in a multiplicity of ways, commander in chief, head of executive branch of government, head of state. And I would say that this is exactly what arab christians do, and until now I assumed that this is what muslims were doing.
But, if you say that their theology supports this, not merely the naming of kids, then so be it.
