`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." He then said, "I have concealed something in my mind which I would like you to tell me" (referring to "the day when the sky will bring forth smoke (dukhan) clearly visible").[1] On his replying, "It is smoke (dukhkh)," he said, "Away with you! You cannot get farther than your rank."[2] `Umar then asked God's messenger if he would permit him to cut off his head, but he replied, "If he is the one[3] you will not be given power over him, and if he is not, you will not do well in killing him." Ibn `Umar told that sometime afterwards God's messenger and Ubayy b. Ka'b went towards the palm trees where Ibn Sayyid was, and God's messenger hid behind the palm trunks seeking stealthily to hear something from Ibn Sayyid before he could see him. Ibn Sayyid was lying on his bed in a wrapper from which a murmur issued, and when his mother saw the Prophet hiding behind the palm trunks she said, "Saf '(that being his name), here is Muhammad," whereupon Ibn Sayyad stopped the murmuring, and God's messenger said, "If you had left him alone, he would have made things clear." `Abdallah b. `Umar told that God's messenger stood up among the people, and when he had extolled God - in a fitting manner he mentioned the dajjal and said, "I warn you of him, and there is no prophet who has not warned his people. 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 of information. 3. i.e., the dajjal. (Bukhari and Muslim.)
