´It was narrated that Muhammad bin Saifi said:` "The Messenger of Allah said on the day of Ashura: Is there anyone among you who has eaten today?' They said: Some of us are fasting and some of us are not.' He said: 'Do not eat for the rest of the day, and send word to the people of Al-Al-Arud telling them not to eat for the rest of the day."'

Hadith Takhrij«سنن ابن ماجہ/الصوم41 (1735)، (تحفة الأشراف: 11225) ، مسند احمد 4/388 (صحیح)»
´It was narrated that 'Abdullah bin 'Amr said:` "My father got me married to a woman and he came to visit her and said: 'What do you think of your husband?' She said: 'What a wonderful man he is. He does not sleep at night and he does not break his fast during the day.' He got upset with me and said: 'I got you married to a woman from among the Muslims and you have neglected her.' I did not pay attention to what he said because of my energy and love of worship. News of that reached the Prophet and he said: 'But I stand (in prayer) and I sleep, I fast and I break my fast. So stand (in prayer) and sleep, fast and break your fast.' He said: 'Fast three days of every month.' I said: 'I am able to do more than that.' He said: 'O bserve the fast of Dawud, peace be upon him: fast one day and break your fast one day.' I said: 'I am able to do more than that.' He said: 'Read the Quran (once) every month.' Then it ended up being every fifteen days, and I still said: 'I am able to do more than that."' '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."
