Sayyiduna Abu Huraira (may Allah be pleased with him) narrated that the Prophet (peace and blessings of Allah be upon him) said twice: "Avoid continuous fasting (wisal), avoid continuous fasting (wisal)." It was asked, "But you observe wisal?" He replied, "At night my Lord feeds me and gives me drink. So, undertake only as much hardship as you have strength for."
