Narrated by Ibn 'Umar (Allah be pleased with both of them)
Ibn 'Umar (Allah be pleased with both of them) said that the Apostle of Allah (may peace be upon him) forbade uninterrupted fasting. They (some of the Companions) said: You yourself fast uninterruptedly, whereupon he said: I am not like you. I am fed and supplied drink (by Allah).
