Musnad Ahmad 1153:1838

Hajjaj narrated to us, he said: Layth narrated to us, Yazid ibn Abi Habib narrated to me, from Abu Bakr ibn Ishaq ibn Yasar, from Abdullah ibn Urwah, from Urwah, from Aisha, that she said: When the Messenger of Allah, peace and blessings of Allah be upon him, arrived in Medina, his companions fell ill, and Abu Bakr fell ill, and Amir ibn Fuhayrah, the freed slave of Abu Bakr, and Bilal. Aisha sought permission from the Messenger of Allah, peace and blessings of Allah be upon him, to visit them, and he gave her permission. She said to Abu Bakr: "How do you find yourself?" He said: Every man wakes up among his family, While death is nearer than the strap of his sandal. And she asked Amir, and he said: I found death before tasting it, Indeed, the coward’s doom is from above him. And she asked Bilal, and he said: Oh, would that I knew if I shall spend a night, In a valley with Idhkhir and Jalil grass around me. So I came to the Messenger of Allah and informed him of their words. He looked toward the sky and then said: "O Allah, make Medina beloved to us as You made Mecca beloved to us, and make it stronger, and bless for us its Sa’ and its Mudd, and transfer its fever to Mahya’ah, which is Al-Juhfah, as they claim."
