Shawwāl is the month between the holy months but Allāh ﷻ has placed His ﷻ gifts in it for us as well. Allāh ﷻ rewards us for our fasting of Ramaḍān and six days in Shawwāl as if fasting the whole year. Many fasted their whole life (Ṣā’imu d-Dahr) like S ‘Ā’ishah (ra). Allāh ﷻ accepts Ramaḍān and the six days like Ṣā’imu d-Dahr.
