Thunderbolt

The triliteral root ṣād ʿayn qāf (ص ع ق) occurs in the Quran 11 times.

(2:19) Or like a storm from the sky, in it are darkness, thunder, and lightning. They place their fingers in their ears from thunderclaps (Arab. الصَّوَاعِقِ, l-ṣawāʿiqi) out of fear of death; and God is aware of the ingrates.

(2:55) When you said, "O Moses, we will not acknowledge you until we see God publicly!" the thunderbolt (Arab. الصَّاعِقَةُ, l-ṣāʿiqatu) took you while you were still staring.

(4:153) The People of the Book ask you to bring down to them a book from the Heaven. They had asked Moses for even more than that, for they said, "Let us see God publicly!", so the thunderbolt (Arab. الصَّاعِقَةُ, l-ṣāʿiqatu) took them for their wickedness. Then they took the calf after the proof had come to them, and We pardoned them for this; We gave Moses a clear authority.
