Reflection on the Creation of the Earth

The Shaykh : The earth also contains signs. In the creation of the earth, there are great signs: the seas, the rivers, the valleys, the stones, the mountains, the plains, and other creations of Allah. It contains minerals in the earth as adjacent pieces. You find these pieces neighboring other pieces, differing from them greatly. This is iron, this is lead, this is gold, this is silver, and these are minerals we do not know. So, it contains signs; it contains great signs, as He (Mighty and Majestic) said: For whom? .
