Musannaf Ibn Abi Shaybah 9851 — Continuous fasting without breaking

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said three times: "Beware of continuous fasting (wisal)." The people said: "But you yourself keep the continuous fast?" He said: "I am not like you. I spend the night in such a way that my Lord gives me food and drink. Take upon yourselves only those deeds that you are able to bear."
