12902 - Hushaym narrated to us from Yunus from al-Hasan regarding a man who made fasting (a month) obligatory upon himself (1), he said: (If) (2) he specified a known month, then let him fast it (and consecutively) (3), and if he did not (specify) (4) a known month (or) (5) did not intend it, then let him begin the days and fast thirty days, (for if) (6) he fasted according to (7) the crescent and broke his fast upon its sighting and it was twenty-nine (days) (8), that suffices him, and if he separated (if) (9) he began the days.
