The word as it is recited in the Quran: Mahmoud Khalil Al-Hussary, Yunus 10:5.
Diya in Islam
The Quran uses it for the sun: “It is He who made the sun a radiance (diyaʾ) and the moon a light (nur)” (10:5), and for the Torah given to Musa and Harun, “a radiance and a reminder for the righteous” (21:48).
Meaning of the name Diya
Diyaʾ means intense light that shines by itself, like the sun’s, whereas nur rather means received, reflected light according to several commentators. The name is given alone or in compounds: Diyaʾ al-Din, “light of the religion”. In Turkey and South Asia it is pronounced Ziya or Zia.
It is He who made the sun a shining light and the moon a derived light and determined for it phases - that you may know the number of years and account [of time]. Allāh has not created this except in truth. He details the signs for a people who know.
Say, "Have you considered: if Allāh should make for you the night continuous until the Day of Resurrection, what deity other than Allāh could bring you light? Then will you not hear?"
