Musnad Abu Ya'la al-Mawsili 3:128

Al-Qawariri narrated to us, Abd al-Rahman ibn Mahdi narrated to us, Shu'bah narrated to us, from al-Hakam, from Yahya ibn al-Jazzar, from Ali: That the Messenger of Allah (may Allah bless him and grant him peace) was sitting on the day of the Confederates (al-Ahzab) at a gap of the trench, and he said: "They distracted us from the middle prayer until the sun set. May Allah fill their houses and their graves—or may Allah fill their bellies and their graves—with fire."
