'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 Messenger of Allah 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.

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدَةُ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ قَدِمْنَا الْمَدِينَةَ وَهْىَ وَبِيئَةٌ فَاشْتَكَى أَبُو بَكْرٍ وَاشْتَكَى بِلاَلٌ فَلَمَّا رَأَى رَسُولُ اللَّهِ ﷺ شَكْوَى أَصْحَابِهِ قَالَ " اللَّهُمَّ حَبِّبْ إِلَيْنَا الْمَدِينَةَ كَمَا حَبَّبْتَ مَكَّةَ أَوْ أَشَدَّ وَصَحِّحْهَا وَبَارِكْ لَنَا فِي صَاعِهَا وَمُدِّهَا وَحَوِّلْ حُمَّاهَا إِلَى الْجُحْفَةِ " .
