Sa'id bin Iyas al-Jariri سعيد بن إياس الجريري · The Book on Fasting

"We were on a journey with the Messenger of Allah. Some of us were fasting and some of us broke their fast. The one who broke their fast had no objection to the one who fasted, and the one who fasted had no objection to the one who broke his fast. They saw that whoever had the strength to fast then that was good, and whoever was weak, then breaking it was better."
