16 Preface قالوا رَبُّنا يَعلَمُ إِنّا إِلَيكُم لَمُرسَلونَYusuf AliThey said: “Our Lord doth know that we have been sent on a mission to you:1Just as a Messenger whose credentials are doubted can refer to the authority granted by his Principal, as the highest proof of his mission, so these messengers of God invoke the authority of God in proof of their mission. In effect they say: “The knowledge of God is perfect, and He knows that our mission is from Him; if you do not, it is your own misfortune.” (R).
