`Abdallah b. `Umar told that `Umar b. al-Khattab went with God's messenger and some of his companions to Ibn Sayyad and found him playing with the boys in the fortress of the B. Maghala, Ibn Sayyid at that time being near the age of puberty. Before he was aware God's messenger gave him a clap on the back and said, "Do you testify that I am God's messenger?" He looked at him and said, "I testify that you are the messenger of the Gentiles," after which Ibn Sayyad said, "Do you testify that I am God's messenger?" The Prophet squeezed him and said, "I believe in God and His messengers." He then asked Ibn Sayyad what visions he had, and when he replied, "One who speaks the truth and one who lies comes to me," God's messenger said, "You are confused."

Noah warned his people, but I shall tell you something about him which no prophet has told his people. You must know that he is one-eyed, whereas God is not one-eyed." 1. Quran, 44:10. 2. The idea is that Ibn Sayyid was being tested to see whether he had any supernatural knowledge of what the Prophet had in mind. His use of a different form of the word for smoke put him on the level of a kahin with a defective source ...
