When does the fasting person break his fast?

Question : Abdullah means he says that the adhan (call to prayer) relies on the calendar. Many students of knowledge know that they eat ten minutes before the adhan. He means, regarding breaking the fast, they break it before the sun sets, before the adhan, before the adhan.

Answer : There is no power or might except in Allah. And he sees the sun; what makes him know that it has set? He does not know; he means the setting of the sun, because the calendar means there is a difference between the setting of the sun and the adhan. If a person sees the sun and sees that it has set, let him break his fast, even if the adhan has not been called; there is no problem with that. But for him to say that the mu'adhdhins (callers to prayer) delay it and he will break his fast before the adhan is a mistake, and what makes him know that?
