Abdullah bin Ma'bd عبد الله بن معبد الزماني · The Book of Fasting

"The Messenger of Allah said: 'The one who fasts every day of his life has neither fasted, nor broken the fast."' '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."

"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."

"We were with the Messenger of Allah and we passed by a man. They said: 'O Prophet of Allah, this man has not broken his fast for such and such a time.' He said: 'He has neither fasted nor broken his fast."' '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."
