"By those who drive the clouds in columns" (al-Saffat: 2) means the angels, among whom is the angel of thunder who drives the clouds. And it is said in another verse: "But it will be only one shout" (al-Saffat: 19), meaning the Blast [of the Trumpet].
﴿فالزاجرات زجرا﴾ يَعْنِي: الْمَلَائِكَة، وَمِنْهُم الرَّعْد الْملك الَّذِي يزجُر السَّحَاب؛ وَقَالَ فِي آيَة أُخْرَى: ﴿فَإِنَّمَا هِيَ زَجْرَةٌ وَاحِدَة﴾ يَعْنِي: النفخة
