Allah will put the Heavens on one finger and the earth on one finger, and the trees and the rivers on one finger, and the rest of the creation on one finger, and then will say, pointing out with His Hand, 'I am the King.' "On that Allah's Apostle smiled and said, "No just estimate have they made of Allah such as due to Him. (39.67)
