Description : If you break your fast a few seconds ago, will there be any harm in fasting ?
Last Answer : As far as we know, in the calendar of every sahri and iftar schedule , the time is written with caution two / one minutes back and forth. For example , if the actual time of sunset is at 6:40 ... long as people break their fast at sunset without delay, they will be on welfare. (Sahih Bukhari 1/273)
