Abu Hurairah (RA) reported: The Messenger of Allah ﷺ forbade (his Companions) from observing fast unintermptedly. One of the Muslims said: Messenger of Allah, you yourself observe Saum Wisal. Whereupon the Messenger of Allah ﷺ said: Who among you is like me? I spend night (in a state) that my Allah feeds me and provides me drink. When they (the Companions of the Holy Prophet) did not agree in abandoning the uninterrupted fast, then the Holy Prophet ﷺ also observed this fast with them for a day, and then for a day. They then saw the new moon and he (the Holy Prophet) said: If the appearance of the new moon were delayed, I would have observed more (fasts) with you (and he did it) by way of warning to them as they had not agreed to refrain (from observing Saum Wisal)
