Qur’an 25:61 states that the moon is a “Siraj” (an object giving light from within itself)
تَبَارَكَ الَّذِي جَعَلَ فِي السَّمَاء بُرُوجًا وَجَعَلَ فِيهَا سِرَاجًا وَقَمَرًا مُّنِيرًا (25:61)
25:61 (Asad) HALLOWED is He who has set up in the skies great constellations, and has placed among them a [radiant] lamp and a light-giving moon.
The same word “Siraj” is used for the sun in Qur’an 71:16 indicating that the Qur’an states that the sun and the moon radiate light from within themselves.
وَجَعَلَ الْقَمَرَ فِيهِنَّ نُورًا وَجَعَلَ الشَّمْسَ سِرَاجًا
71:16 (Asad) and has set up within them the moon as a light [reflected]* and set up the sun as a [radiant] lamp?
*Note the dishonesty of the Asad translation using the word “reflected” to trick the reader into believing that the Qur’an knew that the moon reflects light from the sun.
