Sahih Muslim · Hadith 2626

حدثنا عاصم بن النضر التيمي، حدثنا خالد، - يعني ابن الحارث - حدثنا حميد، عن ثابت، عن أنس، - رضى الله عنه - قال واصل رسول الله صلى الله عليه وسلم في أول شهر رمضان فواصل ناس من المسلمين فبلغه ذلك فقال ‏"‏ لو مد لنا الشهر لواصلنا وصالا يدع المتعمقون تعمقهم إنكم لستم مثلي - أو قال - إني لست مثلكم إني أظل يطعمني ربي ويسقيني ‏"‏ ‏.‏

Anas (Allah be pleased with him) reported that the Messenger of Allah (may peace be upon him) observed Saum Wisal during the early part of the month of Ramadan. The people among Muslims also observed uninterrupted fast. This (news) reached him (the Holy Prophet) and he said: Had the month been lengthened for me I would have continued observing Saum Wisal, so that those who act with forced hardness would (have been obliged) to abandon it. You are not like me (or he said): I am not like you. I continue to do so (in a state) that my Lord feeds me and provides me drink.
