Musnad Abu Ya'la al-Mawsili 3:133

Abu Khaythama narrated to us, Yazid bin Harun narrated to us, Hisham narrated to us, from Muhammad, from Ubaydah, from Ali, who said: The Messenger of Allah (peace be upon him) said on the day of the Trench: "May Allah fill their graves and their bellies with fire, just as they distracted us from the middle prayer, the afternoon prayer (Asr), until the sun set."
