And Musa singled out of his people seventy men for Our appointment , then when the earthquake laid hold of them he said . O my Lord ! hadst Thou willed , Thou wouldst have destroyed them afore and me also. wilt Thou destroy Us for that which the foolish ones amongst us have done ! lt is only thy trial , whereby thou sendest astray whomsoever Thou wilt and keepest guided whomsoever Thou wilt .
