The Qissa-i Sanjan, a Persian verse narrative composed in Gujarat around 1600 by a priest named Bahman Kaikobad, is the Parsis' account of their own arrival and it is the community's foundational text in a legal as much as a sentimental sense. It describes refugees leaving Iran after the Arab conquest, waiting at Hormuz, sailing to Diu and then to Gujarat, and asking the local ruler Jadi Rana for asylum. The ruler sent out a vessel of milk filled to the brim, indicating the land was full; the priest added sugar and returned it, signifying that they would mix in without displacing anyone and sweeten what was there. The terms accepted, in the standard telling, were that they adopt the local language, that their women wear the sari, that weddings be held in the evening, that they surrender their weapons — and, crucially for later arguments, that they not proselytise. Modern Parsi orthodoxy cites these conditions as the basis for the prohibition on conversion, and historians note that the text was written some eight centuries after the events it describes.
