Abdullah bin Umar reported that the Prophet ﷺ said regarding a vision he had about the plague of Madinah, "I saw a black woman with disheveled hair leave Madinah and stop at Mahyaah. I interpreted this to mean that the plague of Madinah had been transferred to Mahyaah, which is al-Juhfah."
حدثنا عفان حدثنا وهيب حدثنا موسى بن عقبة
عن رؤيا رسول الله ﷺ في وباء المدينة عن عبد الله بن عمر عن النبي ﷺ قال رأيت امرأة سوداء ثائرة الرأس خرجت من المدينة حتى قامت بمهيعة فأولت أن وباءها نقل إلى مهيعة وهي الجحفة
Its isnad is sahih. Bukhari related it in 12:373,374 with two chains, one via Sulayman bin Bilal and another via Fudayl bin Sulayman. Darimi related it in 2:130 via Ibn Abu Zinad. Tirmidhi related it in 3:252, and Ibn Majah in 2:237,238, both via Ibn Jurayj. All of them narrated from Musa bin Uqba. Tirmidhi said, a sahih gharib hadith. It will come again via Ibn Jurayj at 5976, and via Ibn Abu Zinad at 6216.Mahyaa is spelled with a fatha on the meem, a saakin ha, a fatha on the ya, and the plain ain, and in Fath al-Bari there is an opinion that appears to be shadhdh, that it follows the pattern of "atheemah." Yaqut said, Mahyaa is Juhfa. And it is also said that it is near Juhfa. Hafiz said, I think his statement, "it is Juhfa," is inserted from Musa bin Uqba's own words, for most of the narrations lack this addition. The addition of the word "annahu" is confirmed in a copy in the margin of M.
