The ruling on eating while in doubt about the dawn or the setting of the sun

Question:
Honorable Shaykh, this questioner says: If a Muslim is certain that the dawn has not yet appeared and he eats, but then it becomes clear to him that the dawn has appeared, what is the ruling? And the same applies to the setting of the sun?

Answer:
This has passed by you in the fiqh lesson: if one eats while in doubt about the dawn, his fast is valid. If one eats while in doubt about the dawn, his fast is valid, as long as it does not become clear to him that he ate after the dawn, because the default is the continuation of the night. But if one eats while in doubt about the setting of the sun, his fast is invalid, because the default is the continuation of the day. It is not permissible for him to break his fast until he is convinced that the sun has set; doubt is not sufficient. Yes.
So there is a difference between the two issues: between the one who eats while in doubt about the dawn and nothing becomes clear to him, whose fast is valid because the default is the continuation of the night, and the one who eats while in doubt about the setting of the sun, for whom it is not permissible until he is convinced that the sun has set or he is certain by seeing it, because the default is the continuation of the day.
