If anyone fasts a day for the sake of Allah, Allah shall keep his face away from Hell (the distance of) seventy years None of you should fast on Friday, unless he fasts a day before it or a day after it My close friend advised me to do three things: fast three days of every month, perform the two Rak‘ahs of Duha, and perform the Witr prayer before I go to sleep Fasting three days every month is fasting your entire lifetime The Prophet (may Allah's peace and blessings be upon him) would not fast in any month more than he did in Sha‘bān If I were to live till the next year, I would definitely fast the ninth day The Messenger of Allah (may Allah's peace and blessings be upon him) fasted on the Day of ‘Āshūrā' The Messenger of Allah (may Allah's peace and blessings be upon him) used to leave fasting in a certain month until we would think that he has not fasted at all that month; and he used to fast in another month so much that we would think he has not stopped fasting at all in that month. If one wished to see him praying at night, one could see him (in that state), and if one wished to see him sleeping at night, one could see him (in that state) too The best (voluntary) fast in the sight of Allah is the fast of Dawūd, and the best (voluntary) prayer in the sight of Allah is the prayer of Dawūd. He used to sleep half of the night, stand to pray one third of it, and then sleep one sixth of it, and he used to fast every other day There is no fasting superior to the fast of my brother Dawūd; fasting half of one's life by fasting one day and eating one day The Messenger of Allah (may Allah's peace and blessings be upon him) used to strive to fast on Mondays and Thursdays If you fast three days of the month, then fast the thirteenth, fourteenth and fifteenth Did the Messenger of Allah (may Allah's peace and blessings be upon him) fast three days of each month? Deeds are presented (to Allah) on Monday and Thursday. So, I like my deeds to be presented while I am fasting
