14 Preface يَومَ تَرجُفُ الأَرضُ وَالجِبالُ وَكانَتِ الجِبالُ كَثيبًا مَهيلًاYusuf AliOne Day the earth and the mountains will be in violent commotion. And the mountains will be as a heap of sand poured out and flowing down.1The Judgment is described as a violent commotion which will change the whole face of nature as we know it. Even the hard rock of mountains will be like loose sand running without any cohesion.
