Sahih al-Bukhari 5174

'Urwa related that 'A'isha said, "When the Messenger of Allah, may Allah bless him and grant him peace, came to Madina, Abu Bakr and Bilal came down with a fever. I visited them said, 'Father, how are you? Bilal, how are you?' When Abu Bakr's fever got worse, he would say: 'Every man is struck down among his people in the morning. Death is nearer than the strap of his sandal.' When the fever left Bilal, he raised his voice and said, 'Would that I knew whether I would spend a night in the valley of Makka with the sweet rushes and panic grass around me! Will I one day return to the waters of Majinna? Will the mountains of Shama and Tafil appear to me?'" 'A'isha said, "I went to the Messenger of Allah, may Allah bless him and grant him peace, and told him and he said, 'O Allah! Make us love Madina as much as we love Makka or even more so! O Allah, make it healthy for us and bless us in our sa' and in our mudd. Remove its fever and put it in al-Juhfa!'" Chapter 79. The Book of Medicine I. Allah has not sent down an illness without sending down a cure for it
