He told that God’s Messenger sent his letter to Kisra with ‘Abdallah b. Hudhafa as-Sahmi, ordering him to hand it to the governor of al- Bahrain. The governor of al-Bahrain conveyed it to Kisra, and when he read it he tore it up. Ibn al-Musayyib said that God’s Messenger then invoked a curse on them to the effect that they might be torn into little pieces. Bukhari transmitted it.
