The mountains remember Him, the rivers remember Him, the trees remember Him and many righteous people are occupied with His remembrance. Anyone who does not remember Him with his heart and tongue and does not humble himself before God is humbled by diverse types of torment and chastisement, as a result of Divine decree. According to the Book of God, angels display the highest degree of submission. The same is true of each and every leaf and particle in the earth, as stated in the Holy Quran. Everything is obedient to Him; not even a leaf can fall without God’s command. No medicine can heal without His command, nor can any food provide nourishment without it. Everything prostrates itself at the threshold of God with extreme humility and submission and is engrossed in subservience to Him. Every particle of the earth, the mountains; every droplet of the rivers, the oceans; every leaf of all the trees and plants, including their every element; every particle of man and beast recognise God, obey Him and extol His praise and glory.
(Hazrat Mirza Ghulam Ahmadas, Noah’s Ark, pp. 53-54)
