The sign of the setting of the sun when it disappears

The questioner:
Honorable Shaykh, during the late hours, especially in the long evenings, the believer does not hear the call from his place, and there is no calendar.

The Shaykh:
No.

The questioner:
There is a calendar.

The Shaykh:
Yes.

The questioner:
And the disappearance is that it be from the shadow of the sun that it flees, so how is it in these matters?

The Shaykh:
The Messenger (peace and blessings be upon him) says here and the sun sets from here. So the sign of the setting of the sun is the coming of the night from the east, the coming of the darkness from the east. As for if it disappears behind a mountain or in dunes or in something and nothing comes from the east, then this does not inform the fasting person. It is necessary for two things to occur: the disappearance of the sun from the direction of the west and the coming of the night from the direction of the east. If the night comes from here, meaning from the east, and the day departs from here, meaning from the west, and the sun has set, then the fasting person has broken his fast. So you observe the east; if you see darkness in it along with the disappearance of the sun from the direction of the west, then it is the place of the zenith. But if it disappears from the west and you do not see darkness from the direction of the east, then he does not break his fast at that moment based on that.
