He said, “By Allah, this is not the speech of a king. I am inclined to think the man is a prophet, just as he claims. Still, we shall wait and see whether his prediction comes to pass: if it proves true, there will be no room for doubt—he is indeed a prophet sent by God. But if it does not, we shall decide the matter for ourselves.”

It was not long before a letter from Shirawayh reached Badhan:

“To proceed: I have killed Chosroes, and I slew him only out of anger for Persia, for he had made the blood of its nobles lawful and was sending them off to his expeditions. When this letter of mine reaches you, secure the allegiance of those under your authority for me. As for the man about whom Chosroes wrote to you, do not disturb him until my further orders reach you.”

When Shirawayh’s letter arrived, Badhan said, “The man is truly the Messenger of Allah.” He embraced Islam, and the Abnaʾ—the Persians residing in Yemen—embraced it with him.
