The Messenger of Allah ﷺ as saying: Do not observe perpetual fasting. If any of you wants to observe perpetual fast, he should observe it until the dawn. They (the people) asked: You observe perpetual fast ? He replied: My position is not like that of yours. There is One Who gives me to eat, and there is One who gives me to drink. (Using translation from Abū Dāʾūd 2361)
أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ «لَا تُوَاصِلُوا فَأَيُّكُمْ يُرِيدُ أَنْ يُوَاصِلَ فَلْيُوَاصِلْ إِلَى السَّحَرِ» قَالُوا إِنَّكَ تُوَاصِلُ يَا رَسُولَ اللَّهِ قَالَ «إِنِّي أَبِيتُ لِي مُطْعِمٌ يُطْعِمُنِي وَيَسْقِينِي»
