17رَبُّ المَشرِقَينِ وَرَبُّ المَغرِبَينِAli UnalHe is the Lord of the two easts, and the Lord of the two wests.1This verse emphasizes the fact that it is God Who has absolute authority and control over the whole universe. By the two easts and two wests, the Qur’ān may be suggesting the rising and setting points of the sun on the longest and shortest days of the year, between which there are 178 such points, which is what verse 37: 5 refers to. It may also suggest that the sun rises in one hemisphere while it sets in another, thus having two points of rising and setting throughout the whole world. Moreover, it also indicates that the sun rises and sets in the same place two days in a year.
