يَوْمَئِذٍ يَتَّبِعُونَ ٱلدَّاعِىَ لَا عِوَجَ لَهُۥ ۖ وَخَشَعَتِ ٱلْأَصْوَاتُ لِلرَّحْمَـٰنِ فَلَا تَسْمَعُ إِلَّا هَمْسًا Qur’an Ta-Ha (20:108)Yawmaithin yattabiAAoona alddaAAiya la AAiwaja lahu wakhashaAAati alaswatu lilrrahmani fala tasmaAAu illa hamsan
Lit., "the caller in whom there will be no deviation (la 'iwaja lahu)" - i.e., the summons to the Last Judgment.
This can also mean “footsteps.”
The Caller: the angel whose voice will call and direct all souls.
A beautiful personification of hushed Sound. First there is the loud blast of the Trumpet. Then there is the stillness and hush of awe and reverence: only the tramp of the ranks marching along will be heard.
