This is from a Twitter thread by Sean W. Anthony where he shows to an article by Robert Hoyland you all know:
"Reflections on the Identity of the Arabian Conquerors
of the Seventh-Century Middle East"
http://www.middleeastmedievalists.com/wp-content/uploads/2017/11/UW-25-Hoyland.pdfIn this thread, Marijn van Putten question something:
"Firstly, the title only appears on coins in southwest Iran,"
And it appears on hundreds of papyri in Egypt, which I'm sure Hoyland is aware of. Not quite sure what point he is trying to make with that. Are coins different because they are more outwardly addressed?"
https://twitter.com/shahanSean/status/932083692419342336I don't know anything about these papyri from Egypt. Are they important? Is Hoyland writing something wrong?
I thought that the first time Muhammed is mention in any Muslim sources, except the Quran, was on the coin from Iran in the 680s. Is that wrong?
