(11) باب النَّهْىِ عَنِ الْوِصَالِ، فِي الصَّوْمِ
Ibn 'Umar (Allah be pleased with both of them) said that the Messenger of Allah (ﷺ) 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).
