Ibn 'Umar (May Allah be pleased with them) said:
The Messenger of Allah ﷺ prohibited observing continuous fasts beyond one day. The Companions submitted: "But you do it." He replied, "I am not like you. I am given to eat and to drink (from Allah)."

[Al-Bukhari and Muslim].

وعن ابن عمر رضي الله عنهما قال: نهى رسول الله ﷺ عن الوصال. قالوا :إنك تواصل؟ قال: "إني لست مثلكم، إني أُطعم وأُسقى" ((متفق عليه)). ، وهذا لفظ البخاري.
