Musnad Abu Ya'la al-Mawsili 3:126

Ubayd Allah ibn Umar ibn Maysarah al-Qawariri narrated to us, Hammad ibn Zayd narrated to us, Asim ibn Bahdalah narrated to us, from Zirr ibn Hubaysh, from Ali, who said: The Messenger of Allah (may Allah bless him and grant him peace) said on the day of the Trench: "May Allah fill their houses and their graves with fire, just as they distracted us from the middle prayer." Hammad said: I do not know if it is from the Prophet (may Allah bless him and grant him peace) or from Ali, and it is the Asr (afternoon) prayer.
