Hadith 1973

Abu Huraira reported God’s messenger as saying, “None of you must fast one day or two days just before Ramadan, except in the case of a man who has been in the habit of observing a particular fast, for he may fast on that day.”* *If a man is in the habit of fasting on a particular day of the week and one or other of the two days before Ramadan falls on that day, he may observe his usual practice. (Bukhari and Muslim.)
