Is there an exception allowing the Prophet (PBUH) to practice continuous fasting?
General Chapter
Al-Mughni
Book of Fasting
Primary text
The Prophet Muhammad (peace be upon him) was permitted to practice continuous fasting because he was uniquely sustained spiritually by Allah, as indicated by his statement, "Indeed, I am not like you; I am fed and given drink," or "My Lord feeds me and gives me to drink." This spiritual sustenance exempted him from the worldly need for food and drink that others possess.

Ibn al-Zubayr reportedly practiced Wisaal, following the example of the Messenger of Allah.
