The non-equivalence of dawn and sunset in determining the time of their onset

His second question: 'Abd al-Karim from the Northern Borders says: Is there a definitive, absolute limit for the dawn, just as there is for breaking the fast at the Maghrib adhan, or is there some leniency in it? Because we see many people saying: "The dawn is not like the evening."
Answer: You are telling the truth. It is obligatory to distinguish the dawn. Once the dawn becomes clear, for Allah said: [Surat al-Baqarah: 187].
So it is obligatory to distinguish the dawn. As long as there is doubt about the dawn, people may eat and drink until the dawn becomes clear. In the east, a clear dawn appears. The true dawn appears on the horizon and spreads to the right and left, and it remains and its light increases. This is the true dawn. As for the false dawn, it stretches on the horizon and then it goes and fades away. As for the setting of the sun, it is known. When the mu'adhdhin calls for the setting of the sun, people break their fast. And if the sun sets and he is in the wilderness and sees it set, he breaks his fast. It is clear. The matter of the sun is clear; its setting is clear. But the dawn may be confused by people with the false dawn, for there is a false dawn that is a pillar, and as he said ............. it is a standing, bright pillar, and then it goes and fades into darkness. Then the true dawn comes after it. So the true dawn is the one upon which the reliance is placed; it is the one that stretches on the horizon and spreads. Thus it extends in the direction of the horizon to the right and left until it becomes a rectangle and its light increases and its light becomes clear. This is the true one. Yes.
