Hadith 4:721
Ibn Numayr narrated to us, he said: Ubayd Allah ibn Umar narrated to us, from Nafi, from Ibn Umar, that the Prophet (peace and blessings of Allah be upon him) fasted continuously (wisal) in Ramadan, so the people fasted continuously. He forbade them, so it was said to him: "You fast continuously." He said: "I am not like you; I am fed and given to drink."
