Musnad Ahmad 32:494

Abu al-Nadr narrated to us, al-Mubarak narrated to us, from Thabit al-Bunani, from Anas, who said: When Fatimah said that—meaning when the Messenger of Allah (peace and blessings of Allah be upon him) experienced the distress of death that he experienced—Fatimah said: "Oh, the distress!" The Messenger of Allah (peace and blessings of Allah be upon him) said: "O my daughter, there has come upon your father that which Allah will not spare anyone from, until the meeting of the Day of Resurrection."
