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.
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
