Musnad Abi Ya'la 7190 — when the Messenger of Allah ﷺ passed away

Amir (may Allah have mercy on him) narrates that when the Messenger of Allah (peace and blessings be upon him) passed away and those of the people who apostatised did so, a group said: "We will pray, but we will not pay zakah." At this the people said to Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him): "Accept this from them." But he (may Allah be pleased with him) said: "If they refuse to give me even a young goat, I will certainly fight them." So he (may Allah be pleased with him) sent Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) out with an army, and Sayyiduna Adi bin Hatim (may Allah be pleased with him) came with a thousand men of the tribe of Tayyi', until they reached al-Yamamah. The narrator says: Banu Amir had killed the agents appointed by the Messenger of Allah (peace and blessings be upon him) and burned them with fire. So Sayyiduna Abu Bakr (may Allah be pleased with him) wrote to Sayyiduna Khalid (may Allah be pleased with him): "Kill Banu Amir and burn them with fire." He did so, until the women cried out. Then he moved on until he reached a spring of water, where people came out before him and called out: "Allahu akbar, Allahu akbar, nashhadu an la ilaha illallah, nashhadu anna Muhammadan rasulullah" (Allah is the Greatest, Allah is the Greatest; we bear witness that there is no god but Allah, and we bear witness that Muhammad is the Messenger of Allah). When Sayyiduna Khalid (may Allah be pleased with him) heard this, he held back from them. Then Sayyiduna Abu Bakr (may Allah be pleased with him) ordered him to march until he camped at al-Hirah, and then to set out from there for Syria. When he camped at al-Hirah, he wrote to the people of Persia and said: "I would like not to leave this place until I have struck fear into them." So he raided them until he reached Sura, where he killed and took captives; then he attacked Ayn al-Tamr and there too killed and took captives; then he set out for Syria. Amir (may Allah have mercy on him) says: Ibn Buqaylah brought out before me that letter of Sayyiduna Khalid (may Allah be pleased with him), in which was written: "In the name of Allah, the Most Gracious, the Most Merciful. From Khalid bin al-Walid to the chiefs of the people of Persia. Peace be upon whoever follows guidance. To proceed: I praise Allah, besides whom there is no true god, with praise of the One who has torn apart your sanctities, scattered your unity, broken your strength and stripped you of your kingdom. So when this letter of mine reaches you, take a covenant of protection from me, pay me the jizyah, and send me hostages as a pledge. Otherwise, by Allah besides whom there is no god, I will confront you with a people who love death as you love life. Peace be upon whoever follows guidance." From a scholarly and technical point of view, the chain of this narration contains the narrator Mujalid bin Sa'id, who is weak, and the chain is also broken (munqati') because Amir al-Sha'bi did not hear from Sayyiduna Khalid bin al-Walid (may Allah be pleased with him).
