1. 2:17 مَثَلُهُمْ كَمَثَلِ ٱلَّذِى ٱسْتَوْقَدَ نَارًا فَلَمَّآ أَضَآءَتْ مَا حَوْلَهُۥ ذَهَبَ ٱللَّهُ بِنُورِهِمْ وَتَرَكَهُمْ فِى ظُلُمَٰتٍ لَّا يُبْصِرُونَ

   Their parable is like the parable of one who kindled a fire but when it had illumined all around him, Allah took away their light, and left them in utter darkness-- they do not see.
   

2. 2:20 يَكَادُ ٱلْبَرْقُ يَخْطَفُ أَبْصَٰرَهُمْ كُلَّمَآ أَضَآءَ لَهُم مَّشَوْا۟ فِيهِ وَإِذَآ أَظْلَمَ عَلَيْهِمْ قَامُوا۟ وَلَوْ شَآءَ ٱللَّهُ لَذَهَبَ بِسَمْعِهِمْ وَأَبْصَٰرِهِمْ إِنَّ ٱللَّهَ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ

   The lightning almost takes away their sight; whenever it shines on them they walk in it, and when it becomes dark to them they stand still; and if Allah had pleased He would certainly have taken away their hearing and their sight; surely Allah has power over all things.
   

3. 10:5 هُوَ ٱلَّذِى جَعَلَ ٱلشَّمْسَ ضِيَآءً وَٱلْقَمَرَ نُورًا وَقَدَّرَهُۥ مَنَازِلَ لِتَعْلَمُوا۟ عَدَدَ ٱلسِّنِينَ وَٱلْحِسَابَ مَا خَلَقَ ٱللَّهُ ذَٰلِكَ إِلَّا بِٱلْحَقِّ يُفَصِّلُ ٱلْءَايَٰتِ لِقَوْمٍ يَعْلَمُونَ

   He it is Who made the sun a shining brightness and the moon a light, and ordained for it mansions that you might know the computation of years and the reckoning. Allah did not create it but with truth; He makes the signs manifest for a people who
   

4. 21:48 وَلَقَدْ ءَاتَيْنَا مُوسَىٰ وَهَٰرُونَ ٱلْفُرْقَانَ وَضِيَآءً وَذِكْرًا لِّلْمُتَّقِينَ

   And certainly We gave to Musa and Haroun the Furqan and a light and a reminder for those who would guard (against evil).
   

5. 24:35 ٱللَّهُ نُورُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ مَثَلُ نُورِهِۦ كَمِشْكَوٰةٍ فِيهَا مِصْبَاحٌ ٱلْمِصْبَاحُ فِى زُجَاجَةٍ ٱلزُّجَاجَةُ كَأَنَّهَا كَوْكَبٌ دُرِّىٌّ يُوقَدُ مِن شَجَرَةٍ مُّبَٰرَكَةٍ زَيْتُونَةٍ لَّا شَرْقِيَّةٍ وَلَا غَرْبِيَّةٍ يَكَادُ زَيْتُهَا يُضِىٓءُ وَلَوْ لَمْ تَمْسَسْهُ نَارٌ نُّورٌ عَلَىٰ نُورٍ يَهْدِى ٱللَّهُ لِنُورِهِۦ مَن يَشَآءُ وَيَضْرِبُ ٱللَّهُ ٱلْأَمْثَٰلَ لِلنَّاسِ وَٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمٌ

   Allah is the light of the heavens and the earth; a likeness of His light is as a niche in which is a lamp, the lamp is in a glass, (and) the glass is as it were a brightly shining star, lit from a blessed olive-tree, neither eastern nor western, the oil whereof almost gives light though fire touch it not-- light upon light-- Allah guides to His light whom He pleases, and Allah sets forth parables for men, and Allah is Cognizant of all things.
   

6. 28:71 قُلْ أَرَءَيْتُمْ إِن جَعَلَ ٱللَّهُ عَلَيْكُمُ ٱلَّيْلَ سَرْمَدًا إِلَىٰ يَوْمِ ٱلْقِيَٰمَةِ مَنْ إِلَٰهٌ غَيْرُ ٱللَّهِ يَأْتِيكُم بِضِيَآءٍ أَفَلَا تَسْمَعُونَ

   Say: Tell me, if Allah were to make the night to continue incessantly on you till the day of resurrection, who is the god besides Allah that could bring you light? Do you not then hear?
