Muhammad ibn al-Muthanna and Muhammad ibn Bashshar narrated to us — and the wording is that of Ibn al-Muthanna — they said: Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Ghaylan ibn Jarir, who heard 'Abdullah ibn Ma'bad al-Zimmani, from Abu Qatadah al-Ansari, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, was asked about his fasting. He said: The Messenger of Allah, peace and blessings be upon him, became angry. Then 'Umar, may Allah be pleased with him, said: "We are pleased with Allah as Lord, with Islam as religion, with Muhammad as Messenger, and with our pledge as a pledge of allegiance." He said: Then he was asked about fasting perpetually, and he said: "He neither fasted nor broke his fast" — or "he did not fast and did not break his fast." He said: Then he was asked about fasting two days and breaking the fast one day, and he said: "And who has the strength for that?" He said: And he was asked about fasting one day and breaking the fast two days, and he said: "Would that Allah gave us strength for that." He said: And he was asked about fasting one day and breaking the fast one day, and he said: "That is the fast of my brother Dawud, peace be upon him." He said: And he was asked about fasting on Monday, and he said: "That is a day on which I was born and a day on which I was sent — or on which revelation was sent down to me." He said: Then he said: "Fasting three days of every month and Ramadan to Ramadan is perpetual fasting." He said: And he was asked about fasting on the Day of 'Arafah, and he said: "It expiates the past year and the remaining one." He said: And he was asked about fasting on the Day of 'Ashura', and he said: "It expiates the past year." And in this hadith, from the narration of Shu'bah, he said: And he was asked about fasting on Monday and Thursday — and we remained silent about mentioning Thursday because we consider it an error.
