concerning the dream of the Prophet ﷺ in Medina: The Prophet ﷺ said, "I saw (in a dream) a black woman with unkempt hair going out of Medina and settling at Mahai'a. I interpreted that as (a symbol of) the epidemic of Medina being transferred to Mahai'a, namely, Al-Juhfa." (Using translation from Bukhārī 7039)   

عَنْ رُؤْيَةِ رَسُولِ اللهِ ﷺ عَنْ عَبْدِ اللهِ بْنِ عُمَرَ عَنِ النَّبِيِّ ﷺ قَالَ رَأَيْتُ امْرَأَةً سَوْدَاءَ ثَائِرَةَ الرَّأْسِ قَدْ خَرَجَتْ مِنَ الْمَدِينَةِ حَتَّى نَزَلَتْ بِمَهْيَعَةَ وَهِيَ الْجُحْفَةُ فَأَوَّلَ رَسُولُ اللهِ ﷺ أَنَّ وَبَاءَ الْمَدِينَةِ قَدْ نُقِلَ إِلَى الْجُحْفَةِ
