(86) باب التَّرْغِيبِ فِي سُكْنَى الْمَدِينَةِ وَالصَّبْرِ عَلَى لأْوَائِهَا
'A'isha (Allah be pleased with her) reported:
When we came to Medina, and it was an unhealthy, uncogenial place, Abu Bakr fell sick and Bilal also fell sick; and when Allah's Messenger (ﷺ) saw the illness of his Companions he said: O Allah, make Medina as congenial to us as you made Mecca congenial or more than that; make it conducive to health, and bleesus in its sa' and in its mudd, and transfer its fever to al-juhfa.
