Narrated `Aisha: When Allah's Apostle emigrated to Medina, Abu Bakr and Bilal had a fever. I entered upon them and said, "O my father! How are you? O Bilal! How are you?" Whenever Abu Bakr got the fever he used to say, "Everybody is staying alive with his people, yet death is nearer to him than his shoe laces." And when fever deserted Bilal, he would recite (two poetic verses): "Would that I could stay overnight in a valley wherein I would be surrounded by Idhkhir and Jalil (two kinds of good smelling grass). Would that one day I could drink of the water of Majinna, and would that Shama and Tafil (two mountains at Mecca) would appear to me!" I went to Allah's Apostle and informed him about that. He said, "O Allah! Make us love Medina as much or more than we love Mecca, and make it healthy, and bless its Sa and its Mudd, and take away its fever and put it in Al-Juhfa." (See Hadith No 558) .

Narrated `Aisha: When Allah's Apostle reached Medina, Abu Bakr and Bilal became ill. When Abu Bakr's fever got worse, he would recite (this poetic verse): "Everybody is staying alive with his People, yet Death is nearer to him than His shoe laces." And Bilal, when his fever deserted him, would recite: "Would that I could stay overnight in A valley wherein I would be Surrounded by Idhkhir and Jalil (kinds of goodsmelling grass). Would that one day I could Drink the water of the Majanna, and Would that (The two mountains) Shama and Tafil would appear to me!" The Prophet said, "O Allah! Curse Shaiba bin Rabi`a and `Utba bin Rabi`a and Umaiya bin Khalaf as they turned us out of our land to the land of epidemics." Allah's Apostle then said, "O Allah! Make us love Medina as we love Mecca or even more than that. O Allah! Give blessings in our Sa and our Mudd (measures symbolizing food) and make the climate of Medina suitable for us, and divert its fever towards Aljuhfa." Aisha added: When we reached Medina, it was the most unhealthy of Allah's lands, and the valley of Bathan (the valley of Medina) used to flow with impure colored water.
