It was narrated from Ibn 'Abbas (رضي الله عنه) that

The Prophet sent his letter to Chosroes with a man and instructed him to give it to the ruler of Bahrain, and the ruler of Bahrain gave it to Chosroes. When he read it, he tore it up. He (the narrator) said: I think Ibn al-Musayyab said: The Messenger of Allah (ﷺ) prayed against them, that they would be utterly torn apart.
