It is narrated from Amir al-Sha'bi (may Allah have mercy on him) that the Rightly Guided Caliph Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him), in the days of the Battle of Yamamah and the ending of the apostasy (riddah), sent Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) a written order to advance towards al-Hirah and then proceed from there towards Syria. When Sayyiduna Khalid (may Allah be pleased with him) encamped at al-Hirah, he wrote to the people of Persia and said: "I would like not to move from here until I have struck terror into them." So he launched raids on them until he reached a place called Sura; there he killed the enemy and took captives. Then he raided Ayn al-Tamr, fought there too and took captives, and after that he set off towards Syria.
Imam Amir al-Sha'bi (may Allah have mercy on him) states that Ibn Buqaylah (that is, Abd al-Masih al-Himyari) produced before me the original letter of Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) to the people of Persia, whose text was as follows: Bismillah al-Rahman al-Rahim (In the name of Allah, the Most Gracious, the Ever-Merciful). From Khalid bin al-Walid to the marzubans (chiefs) of Persia. Peace be upon whoever follows guidance. After praise and glorification: I praise Allah, besides whom there is no true god, with praise befitting His majesty, who has shattered your sanctities, broken up your unity, destroyed your might and stripped you of your kingdom. So when this letter of mine reaches you, take from me a covenant of protection (dhimmah), pay the jizyah and send me hostages as surety; otherwise, by the One besides whom there is no god worthy of worship, I will bring against you a people who love death just as you crave life. And peace be upon whoever follows guidance.
The hadith of Nadlah bin Amr (may Allah be pleased with him) concerning the conquest of Hulwan will come, if Allah wills, in the chapter on fitnahs.
