Musnad Ahmad 5:731

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Sulayman, from Abu al-Duha, from Shutayr ibn Shakl, from Ali, from the Prophet (peace and blessings of Allah be upon him): That he said on the day of the Confederates (al-Ahzab): "They detained us from the middle prayer, the afternoon prayer (Asr), until the sun set. May Allah fill their graves and their houses—or their graves and their bellies—with fire." Shu'bah said: "May Allah fill their graves and their houses—or their graves and their bellies—with fire." I do not know if it is in the hadith or if it is not in the hadith; I am in doubt about it.
