"The Prophet heard that I was fasting continually," and he quoted this Hadith. 'Ata said: "I am not sure how he put it, but I think he said: 'There is no fast for one who fats continually." 'Ata said: "someone who heard him told me that Ibn 'Umar (said) that the Prophet said: 'Whoever fasts every day of his life, then he has not fasted."
