The root ف ز ع (f-z-ʿ) in the Quran

لَا يَحْزُنُهُمُ ٱلْفَزَعُ ٱلْأَكْبَرُ وَتَتَلَقَّىٰهُمُ ٱلْمَلَٰٓئِكَةُ هَٰذَا يَوْمُكُمُ ٱلَّذِى كُنتُمْ تُوعَدُونَ ۝١٠٣

They will not be grieved by the greatest terror, and the angels will meet them, [saying], "This is your Day which you have been promised" -

وَيَوْمَ يُنفَخُ فِى ٱلصُّورِ فَفَزِعَ مَن فِى ٱلسَّمَٰوَٰتِ وَمَن فِى ٱلْأَرْضِ إِلَّا مَن شَآءَ ٱللَّهُ وَكُلٌّ أَتَوْهُ دَٰخِرِينَ ۝٨٧

And [warn of] the Day the Horn will be blown, and whoever is in the heavens and whoever is on the earth will be terrified except whom Allāh wills. And all will come to Him humbled.

مَن جَآءَ بِٱلْحَسَنَةِ فَلَهُۥ خَيْرٌ مِّنْهَا وَهُم مِّن فَزَعٍ يَوْمَئِذٍ ءَامِنُونَ ۝٨٩

Whoever comes [at Judgement] with a good deed will have better than it, and they, from the terror of that Day, will be safe.

وَلَا تَنفَعُ ٱلشَّفَٰعَةُ عِندَهُۥٓ إِلَّا لِمَنْ أَذِنَ لَهُۥ حَتَّىٰٓ إِذَا فُزِّعَ عَن قُلُوبِهِمْ قَالُوا۟ مَاذَا قَالَ رَبُّكُمْ قَالُوا۟ ٱلْحَقَّ وَهُوَ ٱلْعَلِىُّ ٱلْكَبِيرُ ۝٢٣

And intercession does not benefit with Him except for one whom He permits. [And those wait] until, when terror is removed from their hearts, they will say [to one another], "What has your Lord said?" They will say, "The truth." And He is the Most High, the Grand.

وَلَوْ تَرَىٰٓ إِذْ فَزِعُوا۟ فَلَا فَوْتَ وَأُخِذُوا۟ مِن مَّكَانٍ قَرِيبٍ ۝٥١

And if you could see when they are terrified but there is no escape, and they will be seized from a place nearby.

إِذْ دَخَلُوا۟ عَلَىٰ دَاوُۥدَ فَفَزِعَ مِنْهُمْ قَالُوا۟ لَا تَخَفْ خَصْمَانِ بَغَىٰ بَعْضُنَا عَلَىٰ بَعْضٍ فَٱحْكُم بَيْنَنَا بِٱلْحَقِّ وَلَا تُشْطِطْ وَٱهْدِنَآ إِلَىٰ سَوَآءِ ٱلصِّرَٰطِ ۝٢٢

When they entered upon David and he was alarmed by them? They said, "Fear not. [We are] two adversaries, one of whom has wronged the other, so judge between us with truth and do not exceed [it] and guide us to the sound path.
