AssalamuAlaikum, I realized I continued eating intentionally some days during adhan, some days a min or two post adhan and some days 10-15 mins post adhan. I don't have exact count of days, however I did continue my fast till maghrib. I only rely on adhan times to keep track an have no actual adhans. I repent my actions and like to know if I should fast a day to recompense or pay zakat-kaffarah or do both.
