The root ص ع ق (ṣ-ʿ-q) in the Quran

أَوْ كَصَيِّبٍ مِّنَ ٱلسَّمَآءِ فِيهِ ظُلُمَٰتٌ وَرَعْدٌ وَبَرْقٌ يَجْعَلُونَ أَصَٰبِعَهُمْ فِىٓ ءَاذَانِهِم مِّنَ ٱلصَّوَٰعِقِ حَذَرَ ٱلْمَوْتِ وَٱللَّهُ مُحِيطٌۢ بِٱلْكَٰفِرِينَ ۝١٩

Or [it is] like a rainstorm from the sky within which is darkness, thunder and lightning. They put their fingers in their ears against the thunderclaps in dread of death. But Allāh is encompassing of the disbelievers.

وَإِذْ قُلْتُمْ يَٰمُوسَىٰ لَن نُّؤْمِنَ لَكَ حَتَّىٰ نَرَى ٱللَّهَ جَهْرَةً فَأَخَذَتْكُمُ ٱلصَّٰعِقَةُ وَأَنتُمْ تَنظُرُونَ ۝٥٥

And [recall] when you said, "O Moses, we will never believe you until we see Allāh outright"; so the thunderbolt took you while you were looking on.

يَسْـَٔلُكَ أَهْلُ ٱلْكِتَٰبِ أَن تُنَزِّلَ عَلَيْهِمْ كِتَٰبًا مِّنَ ٱلسَّمَآءِ فَقَدْ سَأَلُوا۟ مُوسَىٰٓ أَكْبَرَ مِن ذَٰلِكَ فَقَالُوٓا۟ أَرِنَا ٱللَّهَ جَهْرَةً فَأَخَذَتْهُمُ ٱلصَّٰعِقَةُ بِظُلْمِهِمْ ثُمَّ ٱتَّخَذُوا۟ ٱلْعِجْلَ مِنۢ بَعْدِ مَا جَآءَتْهُمُ ٱلْبَيِّنَٰتُ فَعَفَوْنَا عَن ذَٰلِكَ وَءَاتَيْنَا مُوسَىٰ سُلْطَٰنًا مُّبِينًا ۝١٥٣

The People of the Scripture ask you to bring down to them a book from the heaven. But they had asked of Moses [even] greater than that and said, "Show us Allāh outright," so the thunderbolt struck them for their wrongdoing. Then they took the calf [for worship] after clear evidences had come to them, and We pardoned that. And We gave Moses a clear authority.

وَلَمَّا جَآءَ مُوسَىٰ لِمِيقَٰتِنَا وَكَلَّمَهُۥ رَبُّهُۥ قَالَ رَبِّ أَرِنِىٓ أَنظُرْ إِلَيْكَ قَالَ لَن تَرَىٰنِى وَلَٰكِنِ ٱنظُرْ إِلَى ٱلْجَبَلِ فَإِنِ ٱسْتَقَرَّ مَكَانَهُۥ فَسَوْفَ تَرَىٰنِى فَلَمَّا تَجَلَّىٰ رَبُّهُۥ لِلْجَبَلِ جَعَلَهُۥ دَكًّا وَخَرَّ مُوسَىٰ صَعِقًا فَلَمَّآ أَفَاقَ قَالَ سُبْحَٰنَكَ تُبْتُ إِلَيْكَ وَأَنَا۠ أَوَّلُ ٱلْمُؤْمِنِينَ ۝١٤٣

And when Moses arrived at Our appointed time and his Lord spoke to him, he said, "My Lord, show me [Yourself] that I may look at You." [Allāh] said, "You will not see Me, but look at the mountain; if it should remain in place, then you will see Me." But when his Lord appeared to the mountain, He rendered it level, and Moses fell unconscious. And when he awoke, he said, "Exalted are You! I have repented to You, and I am the first [among my people] of the believers."

وَيُسَبِّحُ ٱلرَّعْدُ بِحَمْدِهِۦ وَٱلْمَلَٰٓئِكَةُ مِنْ خِيفَتِهِۦ وَيُرْسِلُ ٱلصَّوَٰعِقَ فَيُصِيبُ بِهَا مَن يَشَآءُ وَهُمْ يُجَٰدِلُونَ فِى ٱللَّهِ وَهُوَ شَدِيدُ ٱلْمِحَالِ ۝١٣

And the thunder exalts [Allāh] with praise of Him - and the angels [as well] from fear of Him - and He sends thunderbolts and strikes therewith whom He wills while they dispute about Allāh; and He is severe in assault.

وَنُفِخَ فِى ٱلصُّورِ فَصَعِقَ مَن فِى ٱلسَّمَٰوَٰتِ وَمَن فِى ٱلْأَرْضِ إِلَّا مَن شَآءَ ٱللَّهُ ثُمَّ نُفِخَ فِيهِ أُخْرَىٰ فَإِذَا هُمْ قِيَامٌ يَنظُرُونَ ۝٦٨

And the Horn will be blown, and whoever is in the heavens and whoever is on the earth will fall dead except whom Allāh wills. Then it will be blown again, and at once they will be standing, looking on.

فَإِنْ أَعْرَضُوا۟ فَقُلْ أَنذَرْتُكُمْ صَٰعِقَةً مِّثْلَ صَٰعِقَةِ عَادٍ وَثَمُودَ ۝١٣

But if they turn away, then say, "I have warned you of a thunderbolt like the thunderbolt [that struck] ʿAad and Thamūd.

وَأَمَّا ثَمُودُ فَهَدَيْنَٰهُمْ فَٱسْتَحَبُّوا۟ ٱلْعَمَىٰ عَلَى ٱلْهُدَىٰ فَأَخَذَتْهُمْ صَٰعِقَةُ ٱلْعَذَابِ ٱلْهُونِ بِمَا كَانُوا۟ يَكْسِبُونَ ۝١٧

And as for Thamūd, We guided them, but they preferred blindness over guidance, so the thunderbolt of humiliating punishment seized them for what they used to earn.

فَعَتَوْا۟ عَنْ أَمْرِ رَبِّهِمْ فَأَخَذَتْهُمُ ٱلصَّٰعِقَةُ وَهُمْ يَنظُرُونَ ۝٤٤

But they were insolent toward the command of their Lord, so the thunderbolt seized them while they were looking on.

فَذَرْهُمْ حَتَّىٰ يُلَٰقُوا۟ يَوْمَهُمُ ٱلَّذِى فِيهِ يُصْعَقُونَ ۝٤٥

So leave them until they meet their Day in which they will be struck insensible -
