What is the ruling on estimating the times in a country where there are four hours between sunset and the dawn, and the time for 'Isha' cannot be determined because it overlaps with Maghrib?

The questioner : ... Maghrib is delayed ... twenty-one.
The student: I mean it reaches nineteen, twenty, yes.

The questioner: Yes ... the time for 'Isha' and Fajr overlap.

The Shaykh: How do they overlap, I mean?

The questioner: I mean 'Isha'.

The Shaykh: How much is there between Maghrib and Fajr?

The questioner: Yes.

The Shaykh: What is the time between Maghrib and Fajr?

The questioner: I mean 'Isha'.

The Shaykh: I know what you mean, and I mean what I say. How much is between Maghrib? I am not asking you about what you mean.

The questioner: Eleven ... .

The Shaykh: How much is between Maghrib and Fajr?

The questioner: Four hours ... one and a half in the morning, the dawn is eleven and a half minus five for 'Isha'.
The student: And Maghrib.
The student : ... .

The Shaykh: Okay, Maghrib is nine and a third, and how much is 'Isha'?

The questioner: Eleven and a half minus five.

The Shaykh: How is that? What is the time between Maghrib and 'Isha'?

The questioner: Because here in the summer the differences increase, meaning to a greater extent, and in the winter the differences decrease to a greater extent.

The Shaykh: No problem with the differences.

The questioner : ... .

The Shaykh: The differences.

The questioner: ... a real time, but a time ... .

The Shaykh : How?

The questioner: 'Isha' ... is not a real time, but a time ... because on a day of the year there is no time for 'Isha' and a time for Maghrib that are distinct.

The Shaykh: I have returned to what I started with, this is what I care about, but I say, tell me how much is between sunset and the dawn?

The questioner : ... .

The Shaykh: As the brother said, between Maghrib and Fajr is four hours.

The questioner: Yes.

The Shaykh: Okay, so you said just now that between 'Isha' and Fajr is one and a half hours, this does not make sense, if between Maghrib and Fajr is four hours, if that is the case, it is not reasonable that between 'Isha' and Fajr is one and a half hours.

The questioner: It is like this ... also the time for Fajr is not ... because they overlap, so they took these times for 'Isha' and Fajr until ... .

The Shaykh: Okay, is this the Sharia ruling?

The questioner : I do not know.

The Shaykh: That you take the timing from astronomy, then it is not related to the country you are in, but you measure, as I said, this country against another country, and there may be some difference between them, little or much, but the reality is that if a person knows the Sharia, the matter is easy for him.

The questioner: ... the sky is red from after sunset to the sunrise.

The Shaykh: Yes, this is what I want to understand, this is what I want to understand well, is this every day? On clear days, as soon as the sun sets, the red twilight appears and continues until the dawn.

The questioner : ... .

The Shaykh: Does this twilight not disappear at all before that? And on your honor? Okay, in that case, estimation is necessary, but the estimation mentioned, I believe, is not sound, even from the astronomical point of view, because the other country that we will make the basis to measure our time in the town where one of the two times is not distinguished from the other, do you see, is it the same there? The difference between the time for Maghrib and Fajr is four hours, and the time between 'Isha' and Fajr is one and a half hours?

The questioner: No.

The Shaykh : So.

The questioner: I mean calculated on ... .

The Shaykh: No, we now want to apply, estimate, an estimation that has no relation to astronomy at all now, and I personally do not see relying on astronomy because it is specific to a certain class of people, the educated, while Islam has made it easy so that it can be known and applied by all people, regardless of their culture, and the proportion of difference between their concepts and minds and so on. So we have a principle here to solve the problem, it is not permissible for us to go beyond it to a means to which the Wise Lawgiver has not directed us. It was reported in the authentic hadith that the Prophet (peace and blessings be upon him), when he informed his companions about the Great Dajjal, said: .
So the question was asked: In the first three days, the one whose length is a year, the one whose length is a month, and the one whose length is a week, is five prayers sufficient in this day? Is one day whose length is a year sufficient for five prayers? He said: No, so estimate for it its measure. So estimation is needed here, and estimation here is also made easy for the general Muslims. For example, how many prayers are there in a year? Three hundred and sixty-five multiplied by five, the result is, I don't know how much, so we need to divide this result by these days, so you pray five prayers every day, with varying proportions in terms of time, because, for example, the time between Maghrib and 'Isha' in all this world is much closer than the time between 'Asr and Maghrib, and likewise between Dhuhr and 'Asr, and closer than all of that is the time between sunrise and Dhuhr, so this is a long time for the Fajr prayer and the Dhuhr prayer. On a day we estimate, we do not say between the Fajr prayer and the Dhuhr prayer, for example, three hours; because the custom is that the difference is six hours, seven hours. Likewise, we cannot estimate between the Maghrib prayer and the 'Isha' prayer five hours, this does not exist in the world.
So we need to pray in the day whose length is a year, so many prayers, and then not pray them, gathering them all in one hour, this is not possible. Rather, we estimate that in every twenty-four hours we pray five prayers, and then we estimate times close to reality between each prayer and the next, so the problem is solved in these countries where the sun is not seen or the red twilight is not seen. So it is not correct for us to make the time between Maghrib and 'Isha' two and a half hours, and between 'Isha' and Fajr one and a half hours, but rather we make the time between the two 'Isha's as close as possible to the reality of the matter for the countries close to us. On this basis, if we want to proceed with the subject of the previous question, is between Maghrib and 'Isha' three and a half hours or two and a half hours? No, let it be one and a half hours at most. In that case, there will remain in the night in which a person takes the pre-dawn meal two and a half hours. So in these two and a half hours, a person can sleep for two hours after the 'Isha' prayer, and he can take the pre-dawn meal in the remaining half hour. And although this has some difficulty for those who have not trained, it is a possible matter and does not have great hardship, except for some people who ... have not previously lived any part of the hardship of life.
