Musnad Ahmad 830:19

Khalaf ibn al-Walid narrated to us, al-Mubarak narrated to us, from al-Hasan, from Abu Bakrah, that he narrated to him, saying: The sun eclipsed during the time of the Prophet, may God bless him and grant him peace, while we were with him. He jumped up in alarm, dragging his garment, and he mentioned the meaning of it.
