Tafsir of An-Nazi'at 79:7

On the Day the Rajifah shakes, followed by the Radifah. Ibn Abbas said, "These are the two blasts (of the Trumpet) -- the first and the second.'' Mujahid, Al-Hasan, Qatadah, Ad-Dahhak and others have made similar statements. It has been reported from Mujahid that he said, "In reference to the first, it is the statement of Allah,

يوم ترجف الراجفة

(On the Day the Rajifah shakes,) This is similar to Allah's statement,

يوم ترجف اﻻرض والجبال

On the Day the earth and the mountains shake. (73:14) The second is Ar-Radifah, and it is like the Allah's statement,

وحملت اﻻرض والجبال فدكتا دكة وحدة

And the earth and mountains shall be removed from their places, and crushed with a single crushing. (69:14)'' Concerning Allah's statement,

قلوب يوميذ واجفة
