The Prophet, peace be upon him, and his Companions used to determine the beginning of the fasting day and its end by looking with the naked eye. It is not correct that one should overburden oneself by meticulously following timetables based upon astronomical calculations. No timetable anywhere in the world should be relied upon completely in judging the beginning of Fajr (i.e. the start of the fast) or the beginning of Maghrib (i.e. the end of the fast). One stops eating at the onset of Fajr, which is determined by looking towards the night sky – and if one sees a horizontally spreading light across the horizon and roof tops that spreads across the skyline, then he stops eating and prepares for the prayer. Also, one should hasten to break the fast once the sun has completely set and not worry about the bright redness in the horizon.
