“It is He who made the sun a shining light and the moon a derived light.”
(Surah: Yunos, verse: 5).
Comment: when Arabians were considering the moon as a shining object without any idea of its darkness, the holy Quran clearly elucidates the reflection of sunlight by the moon with these words NOOR- MOUNIR(reflector- derived light) and DIA-SERADJ (connate light) for moon and sun respectively. (The Holy Quran: 10: 5, 71:16, 25:61, and 91: 1 up to 4)
