6. It is narrated by Imam Ja’far Sadiq that the Holy Prophet (s.a.w.s.) used to fast so much that people used to say that he does not miss any fast. Then he used to discontinue observing fast for so many days that people used to say that he does not observe fast. Then he started observing fast for alternate days like Dawood . When he passed away from this world, he was fasting (one of the three fasts of a month). He said that these fasts are equal to the fasts of an age and it kills the evil thoughts arising in one’s heart.” The narrator asked, “May I be sacrificed on you, what are those days?” Imam replied, “First Thursday of every month, the Wednesday coming after first ten days of a month and last Thursday of the month?” The narrator asked, “Why are these days selected?” Imam replied, “The communities before us had to bear the chastisement on these days. Hence the Holy Prophet (s.a.w.s.) used to fast during these days and they are the days of fearing Allah.”
