Musannaf Ibn Abi Shaybah 35985 — The arrival of Khalid bin al-Walid

Amir al-Sha'bi said: Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) wrote a letter from Hirah addressed to the chiefs of Persia, in which was written: "In the name of Allah, the Most Gracious, the Most Merciful. From Khalid bin al-Walid to the chiefs of Persia. Peace be upon those who follow guidance. I praise before you Allah, besides whom there is no god. All praise is for Allah, who has scattered your forces, divided your assembly and set you at odds with one another. When this letter of mine reaches you, accept the covenant of protection from me and agree to pay the jizyah. If you do not do so, I will come to you with a people who love death as you love life."
