It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) set out for the Conquest of Makkah, he (peace and blessings be upon him) appointed Abu Ruhm Kulthum bin Husayn al-Ghifari (may Allah be pleased with him) as his deputy (governor) over Madinah.

It is narrated from the nephew of Abu Ruhm that he heard Abu Ruhm Kulthum bin Husayn (may Allah be pleased with him), who was one of the Companions who gave the pledge beneath the Tree, say: "I took part in the Battle of Tabuk with the Messenger of Allah (peace and blessings be upon him). One night I was travelling close to him (peace and blessings be upon him) when drowsiness overcame him (peace and blessings be upon him). My mount came very close to the she-camel of him (peace and blessings be upon him), so I began pulling my mount away from him (peace and blessings be upon him), until at some hour of the night sleep overcame me. Then the Messenger of Allah (peace and blessings be upon him) said: 'Indeed, the hardest thing for me concerning my people is that the Muhajirun of Quraysh, the Ansar, and the tribes of Aslam and Ghifar should stay behind from me.'"
