Aisha (Allah be pleased with her) reported: When we came to Madinah, and it was an unhealthy, uncogenial place, Abu Bakr (RA) fell sick and Bilal (RA) also fell sick; and when Allahs Messenger ﷺ saw the illness of his Companions he said: O Allah, make Madinah as congenial to us as you made Makkah congenial or more than that; make it conducive to health, and bless us in its sa and in its mudd, and transfer its fever to al-Juhfa.
