回教的先知穆罕默德带着他的40个门徒在山谷里讲道。他说,信心是成就任何事物的关键。一位门徒说:“你有信心,你能让那座山过来,让我们站在山顶吗?”穆罕默德对他的门徒满怀信心地把头一点,对着山大喊一声:“山过来!”山谷里响起了他的回声。回声终于消失,山谷又归于宁静。大家都聚精会神地望着那座山,穆罕默德说:“山不过来,我们过去吧!” Muhammad, the prophet of Islam, preached in the valley with his 40 disciples. He said that confidence is the key to accomplishing anything. A disciple said: “You have confidence that you can let the mountain come and let us stand on the top of the hill?” Muhammad gave his head to his disciples with confidence and shouted to the mountain, “The mountains come!” in the valley. He echoed his reply. The echo finally disappeared and the valley was quiet again. Everyone was attentively looking at the mountain. Muhammad said: “The mountain is not here. Let’s go!”
