It is narrated from Sayyidah Aisha Siddiqa (may Allah be pleased with her) that when the Messenger of Allah (peace and blessings be upon him) arrived in Madinah Munawwarah, it was a place afflicted with epidemic and the people were suffering from fever. Sayyiduna Abu Bakr (may Allah be pleased with him) fell ill. Whenever his fever intensified, he would say: "Every person wakes up among his family, while death is closer to him than the strap of his sandal." Sayyidah Aisha (may Allah be pleased with her) says that when Sayyiduna Bilal (may Allah be pleased with him) suffered from severe fever, he would say: "If only I could know whether I will ever spend a single night in that valley, where around me would be the grasses called Idhkhir and Jalil, and whether I will ever reach the springs of Majannah, and whether the mountains called Shamah and Jalil will ever appear before me. O Allah! Curse Utbah bin Rabi’ah, Shaybah bin Rabi’ah, and Umayyah bin Khalaf, for they expelled us from Makkah Mukarramah." When the Messenger of Allah (peace and blessings be upon him) saw the distress of these companions, he said: "O Allah! Make Madinah Munawwarah as beloved to us as Makkah Mukarramah, or even more so. And make its climate healthy for us, and bless its Sa’ and Mudd for us, and transfer its fever to Juhfah." Urwah says: The result of this supplication was that any child born in the region of Juhfah would not reach the age of maturity before being struck down by fever.
