Musnad Ahmad 948:3

'Abd al-Razzaq narrated to us, Ibn Jurayj informed us, Hisham ibn 'Urwah informed me, from his father, from 'Abdullah ibn al-Zubayr, from Sufyan ibn Abi Zuhayr al-Bahzi, who said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, say: "Yemen will be conquered, and a people will come driving their camels, carrying their families and those who obey them. And Medina is better for them, if they only knew. Then al-Sham will be conquered, and a people will come driving their camels, carrying their families and those who obey them. And Medina is better for them, if they only knew."
