The Messenger of Allah ﷺ prohibited perpetual fasting. They (the people) said: You keep perpetual fasting, Messenger of Allah. He said: My position is not like that you yours. I am provided with food and drink.  

أَنَّ رَسُولَ اللَّهِ نَهَى عَنِ الْوِصَالِ قَالُوا فَإِنَّكَ تُوَاصِلُ يَا رَسُولَ اللَّهِ قَالَ إِنِّي لَسْتُ كَهَيْئَتِكُمْ إِنِّي أُطْعَمُ وَأُسْقَى  

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.  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ تُوَاصِلُوا فَأَيُّكُمْ أَرَادَ أَنْ يُوَاصِلَ فَلْيُوَاصِلْ حَتَّى السَّحَرِ قَالُوا فَإِنَّكَ تُوَاصِلُ قَالَ إِنِّي لَسْتُ كَهَيْئَتِكُمْ إِنَّ لِي مُطْعِمًا يُطْعِمُنِي وَسَاقِيًا يَسْقِينِي
