9:128. There has come to you O Arabs, a messenger from among your own selves and from your lineage, who is an Arab like you. What is difficult for you is difficult for him. He is concerned about you, calling you to have faith in your Lord, and he is kind and compassionate with the believers.
9:129. If they reject you O Messenger, not believing in what you come with, then say: 'Allah is sufficient for me, there is nothing worthy of worship except Him. I rely on Him alone, and He, Glory be to Him, is the Lord of the Great Throne.'
