عليك السلام و رحمة الله و بركاته
saying of الله the most high:
(40) So I swear by the Lord of [all] risings and settings that indeed We are able
(9) [He is] the Lord of the East and the West; there is no deity except Him, so take Him as Disposer of [your] affairs.
(17) [He is] Lord of the two sunrises and Lord of the two sunsets.
the prophet محمد ﷺ said:
He then commanded and Iqama for the evening prayer was pronounced when the sun had sunk. He then commanded and Iqama for the night prayer was pronounced when the twilight had disappeared. He then delayed the morning prayer on the next day (so much so) that after returning from it one would say that the sun had risen or it was about to rise. He then delayed the noon prayer till it was near the time of afternoon prayer (as it was observed yesterday). He then delayed the afternoon prayer till one after returning from it would say that the sun had become red. He then delayed the evening prayer till the twilight was about to disappear.
know that sunrises and sunsets change during year's days between increasing and decreasing depending on the length of the night and the day as example recently here the day shortned which means sunset decrease. [07:25, 07:24, 07:23 PM]
I mentioned the arguments of religion refer to scholars for fatwae: those who are famous by following and in clinging to the book [quran] and the sunnah [sahiha]
Prayer times are traditionally calculated according to the position of
the sun, regardless of the weather.
what was mentioned by @goldpseudo isn't correct for all times precisly Fajr and Maghreb and scholars talked on that.
