ٱللَّهُ نُورُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ مَثَلُ نُورِهِۦ كَمِشْكَوٰةٍۢ فِيهَا مِصْبَاحٌ ۖ ٱلْمِصْبَاحُ فِى زُجَاجَةٍ ٱللَّهُ نُورُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ مَثَلُ نُورِهِۦ كَمِشْكَوٰةٍۢ فِيهَا مِصْبَاحٌ ۖ ٱلْمِصْبَاحُ فِى زُجَاجَةٍ ۖ ٱلزُّجَاجَةُ كَأَنَّهَا كَوْكَبٌۭ دُرِّىٌّۭ يُوقَدُ مِن شَجَرَةٍۢ مُّبَـٰرَكَةٍۢ زَيْتُونَةٍۢ لَّا شَرْقِيَّةٍۢ وَلَا غَرْبِيَّةٍۢ يَكَادُ زَيْتُهَا يُضِىٓءُ وَلَوْ لَمْ تَمْسَسْهُ نَارٌۭ ۚ نُّورٌ عَلَىٰ نُورٍۢ ۗ يَهْدِى ٱللَّهُ لِنُورِهِۦ مَن يَشَآءُ ۚ وَيَضْرِبُ ٱللَّهُ ٱلْأَمْثَـٰلَ لِلنَّاسِ ۗ وَٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمٌۭ

Allah is The Light of the heavens and the earth; the similitude of His Light is as a niche wherein is a lamp, the lamp in a glass, the glass as it were a glittering planet-kindled from a Blessed Tree, an olive that is neither eastern nor western, whose oil would almost illuminate, even if no fire touched it, Light upon Light; Allah guides to His Light whomever He decides, and Allah strikes similitudes for mankind, and Allah is Ever-Knowing of everything.

Surah Al-Nur, verse 35
