The scholars, may Allah have mercy on them, differed greatly on this issue regarding the exact time of the Friday hour, and there are many opinions about it. Perhaps the most well-known and apparent among them is this.
There are four opinions, and some have counted up to ten, but we say the most famous are two.
The first opinion is that it is in the last hour of the day, and this was narrated from Abu Huraira, and also from Abdullah ibn Abbas and others.
Some say it is the time between the imam sitting and standing, and some say it is between the two khutbahs.
Based on this, we say that the most likely opinion according to the scholars is.
It is the last hour of Friday, the last hour of Friday.
Some say it moves and has no fixed time, it starts from the beginning of the day and ends at its end, and it could be at the beginning, middle, or end, and it is not connected to.
the worship of prayer, not prayer, not connected to the worship of prayer, rather it is broader than that. And Allah knows best.
As for the night and knowing its times, we say that the night begins at sunset and ends at the break of dawn.
The night is divided into thirds, so you calculate the hour when the sun sets, and the hour when dawn breaks, then you divide that time into three thirds.
After that, a person can know the middle third of it. Some people calculate the time from the 'isha prayer, but this is not correct. Rather, we say that the night is counted from sunset.
Then after that, a person determines the time in the middle third of the night, and we cannot specify it by a certain hour because the length of time changes.
Depending on the seasons and their progression or delay, and also their periods, the hour in winter is different from the hour in summer. So we say that what relates to the middle third in that.
It is the middle between sunset and the break of dawn, between them, and that is the middle third. And Allah knows best.
