Musannaf Ibn Abi Shayba 36:283

Yazid ibn Harun narrated to us, he said: Hisham ibn Hassan informed us, from Muhammad, from Ubaydah, from Ali, that the Messenger of Allah (may Allah bless him and grant him peace) said on the day of the Trench: "They detained us from the middle prayer, the afternoon prayer (Asr). May Allah fill their houses and their graves with fire."
