Riyad as-Salihin, Book 1, Hadith 230 (In-Book) ⓘ

'Aishah (May Allah bepleased with her) reported: The Prophet prohibited his Companions out of mercy for them, from observing continuous fasting without a break. They said: "But you observe fast continuously". He replied, "I am not like you. I spend the night while my Rubb provides me with food and drink".[Al-Bukhari and Muslim].(This means that Allah has bestowed upon him the power of endurance like that of a person who eats and drinks).

وعنها رضي الله عنها قالت‏:‏ نهاهم النبي صلى الله عليه وسلم عن الوصال رحمة لهم، فقالوا‏:‏ إنك تواصل‏؟‏ قال‏:‏ ‏"‏إني لست كهيئتكم، إني أبيت يطعمني ربي ويسقيني ‏"‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏ ‏.‏ (11)
