A'isha, the Mother of the Believers (Allah be pleased with her), reported that the Messenger of Allah ( صلی اللہ علیہ وسلم ) used to fast (so continuously) that we said that he would not break, and did not fast at all till we said that he would not fast. And I did not see the Messenger of Allah ( صلی اللہ علیہ وسلم ) completing the fast of a month, but that of Ramadan, and I did not see him fasting more in any other month than that of Sha'ban.
