المزمل · Verse 14 / 20 · Page 574
يَوْمَ تَرْجُفُ الْأَرْضُ وَالْجِبَالُ وَكَانَتِ الْجِبَالُ كَثِيبًا مَّهِيلًا
Yawma tarjuful ardu waljibaalu wa kaanatil jibaalu kaseebam maheelaa
On the Day the earth and the mountains will convulse and the mountains will become a heap of sand pouring down.
That punishment will occur to those who deny on the day when the earth and the mountains will shake and the mountains will become scattered flowing sand because of its extreme horror.
