The delegation and mission to Hamdan

Hamdan came in delegation in 9 AH; the Prophet sent Khalid to call them for six months, then Ali — and they all became Muslim. When the news reached him the Prophet fell prostrate and said: peace be upon Hamdan ¹.

The Hamdan delegation came in 9 AH after the Prophet's return from Tabuk; the Prophet wrote them a document granting what they asked and set Malik ibn al-Namt over those of his people who had become Muslim ². To the rest he sent Khalid ibn al-Walid to call them to Islam; he stayed six months calling them and they did not answer ³. Then he sent Ali ibn Abi Talib, ordering him to relieve Khalid; Ali came to Hamdan, read the Prophet's letter to them and called them to Islam — and they all became Muslim ¹. Ali wrote to the Prophet with the good news of their conversion; when the Prophet read the letter he fell prostrate, then raised his head and said: peace be upon Hamdan, peace be upon Hamdan ⁴.
