Quran 2:257

Allah is the ally of those who believe. He brings them out from darknesses into the light.
And those who disbelieve - their allies are Taghut. (FALSE GOD) They take them out of the light into darknesses. Those are the companions of the Fire; they will abide eternally therein.

اللَّهُ وَلِيُّ الَّذِينَ آمَنُوا يُخْرِجُهُم مِّنَ الظُّلُمَاتِ إِلَى النُّورِ ۖ وَالَّذِينَ كَفَرُوا أَوْلِيَاؤُهُمُ الطَّاغُوتُ يُخْرِجُونَهُم مِّنَ النُّورِ إِلَى الظُّلُمَاتِ ۗ أُولَٰئِكَ أَصْحَابُ النَّارِ ۖ هُمْ فِيهَا خَالِدُونَ
