It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said: ‘How much of the month has passed?” We said: “Twenty-two (days), and there are eight left.” The Messenger of Allah (ﷺ) said: “The month is like that, and the month is like that, (and the month is like that), three times, and he withheld one finger the last time.”
It was narrated from Muhammad bin Sa’d bin Abu Waqqas that his father said: “The Messenger of Allah (ﷺ) said: ‘The month is like that and like that and like that,’ and he showed nine fingers on the third time to indicate twenty-nine.”
It was narrated that Abu Hurairah said: (The months in which) We fasted twenty-nine days at the time of the Messenger of Allah (ﷺ), were more than (the months in which) we fasted thirty days.
