(48) باب الْوِصَالِ، وَمَنْ قَالَ لَيْسَ فِي اللَّيْلِ صِيَامٌ
Narrated Anas:
The Prophet (ﷺ) said, "Do not practice Al-Wisal (fasting continuously without breaking one's fast in the evening or eating before the following dawn)." The people said to the Prophet, "But you practice Al- Wisal?" The Prophet (ﷺ) replied, "I am not like any of you, for I am given food and drink (by Allah) during the night."
