Musannaf Ibn Abi Shayba 23:175

Affan narrated to us, he said: Wuhayb narrated to us, he said: Musa ibn Uqbah narrated to me, he said: Salim narrated to me, regarding the vision of the Messenger of Allah, may Allah bless him and grant him peace, concerning the epidemic of Medina, from Abdullah ibn Umar, from the Prophet, may Allah bless him and grant him peace, who said: "I saw a black woman with disheveled hair who left Medina until she was cast into Mahya'ah. I interpreted that the epidemic of Medina was transferred to Mahya'ah."
