Musnad Abu Ya'la al-Mawsili 150:72

Suwayd ibn Sa'id narrated to us, Muhammad ibn 'Abd al-Rahim ibn Sharus al-Halabi narrated to us, from Ibn Mina, from his father, from 'Aishah, who said: I saw the Prophet, may Allah bless him and grant him peace, embrace 'Ali and kiss him, and he was saying: "May my father be sacrificed for the unique martyr, may my father be sacrificed for the unique martyr."
