In Surat Al-Baqarah, verse 115, Allah says:
Here, Allah says that he owns Al-Mashriq (literally: the east/sunrise), in the Arabic singular form, المشرق .
In Surah Ar-Rahman, verse 17, Allah says:
Here, Allah says that he is Lord of Al-Mashriqayni (literally: the two easts/sunrises), in the Arabic dual form, المشرقين.
In Surah As-Saffaat, verse 5, Allah says:
Here, Allah says that he is Lord of Al-Mashaariq (literally: the multiple easts/sunrises), in the Arabic plural (3+) form, المشارق.
Since parts of the Qur'an explain other parts, what exactly do the scholars of tafseer (the mufassireen) explain as the interpretation of these three ayat when you look at them together as a set?
