Natan’el al-Fayyumi - Wikipedia
Like the Ismailis, Natan’el argued that God sent different prophets to the various nations of the world, containing legislations suited to the particular temperament of each individual nation. Each people should remain loyal to its own religion, because the universal teaching was adapted to the specific conditions and experiences of each community. Not all Jewish depictions of Muhammad were negative. Jews who lived in environments governed by Ismailis did not view them as enemies, and vice versa.
A thousand years ago. Feels like it.
