(When they will be commanded to devastate the system of the universe) that Day, everything in motion (in the universe) will tremor into violent convulsion
"On the Day when the (first) earthquake (violently) shakes everything [i.e. the blast of the trumpet sounded by the Angel Isr?f?l on the Last Day which will cause every living being to die],"
Sayyed Abbas Sadr-Ameli
The Day on which everything that can be in commotion will be in violent commotion
Al-muntakhab fi tafsir al-Qur'an al-Karim
The day shall come when the trumpet is sounded and the universe goes into a violent convulsion
