Musnad Abu Ya'la al-Mawsili 105:13

Al-Qawariri narrated to us, Yusuf ibn al-Majishun narrated to us, my father narrated to me, from Abu Ubaydah ibn Muhammad ibn Ammar ibn Yasir, from a freedwoman of Ammar ibn Yasir, who said: Ammar suffered an illness that weighed heavily upon him, and he fainted. Then he regained consciousness while we were weeping around him. He said: "What makes you weep? Do you fear that I will die in my bed? My beloved, may Allah bless him and grant him peace, informed me that the transgressing party would kill me, and that the last of my provision would be a sip of milk."
