Delegation of Banū Murrah
Al-Wāqidī (2) states that they arrived in the ninth year, upon the Prophet’s return from Tabūk. They were thirteen men, among them al-Ḥārith ibn ʿAwf. The Messenger of Allah ﷺ rewarded the delegation with ten ounces of silver and gave al-Ḥārith ibn ʿAwf twelve ounces. They mentioned that their land was stricken with drought, so he prayed for them, saying:

“O Allah, send them rainfall.”

When they went back to their homeland, they found that it had rained on the very day the Messenger of Allah ﷺ had supplicated for them.

They were ten men, among them Suwāʾ ibn al-Ḥārith (9) and his son Khuzaymah ibn Suwāʾ. They were lodged in the house of Ramlah bint al-Ḥārith, and Bilāl used to bring them lunch and supper. They embraced Islam, declaring, “We stand surety for those behind us.” No one during those seasons had been rougher or harsher toward the Messenger of Allah ﷺ than they. Among the delegation was a man whom the Messenger of Allah recognized
