question #3 Sahih Muslim 1158, Book 13, Hadith 234 : How does the Prophet’s approach to fasting reflect on the concept of moderation in Islam?

Anas (Allah be pleased with him) reported that the Messenger of Allah (ﷺ) used to observe fast till it was said that he had observed fast, he had observed fast (perhaps never to break it), and he did not fast till it was said that he had given up fast, he had given up fast (perhaps never to observe it).
