Musnad Ahmad 941:68

'Abd al-Razzaq narrated to us, Ma'mar narrated to us, from al-Zuhri, from 'Urwah, from Usamah, who said: The Prophet, may Allah bless him and grant him peace, looked out from one of the fortresses of Medina and said: "Do you see what I see?" They said: "No." He said: "Indeed, I see the tribulations falling amidst your houses like the falling of rain."
