The questioner : Shaykh, may Allah reward you. Regarding the disappearance of the sun, does the meaning refer to its disappearance from the country? Because in some places facing long mountains, the sun may be behind them, and it is not known whether it has set or not...
The Shaykh : No, no. The intended meaning is its obscuring by the mountains. If we said that, a person would enter his room after the midday prayer and break his fast.
The questioner : ... .
The Shaykh : They cannot determine it. The night becomes clear to you. The night is distinguished by the Shari'ah.
The questioner : ... .
The Shaykh : That is, the night has become clear. The night is distinguished, and the sun has not set; its disk has not set. But when the sun sets, the black line extends from north to south. If it has set, that is the sign. Yes.
