Sahih Adab al-Mufrad

738/(958/1) From Abdullah ibn Umar: That Umar ibn al-Khattab set out with the Messenger of Allah, peace and blessings be upon him, with a group of his companions towards Ibn Sayyad, until they found him playing with the boys in the enclosure of Banu Maghala, and at that time Ibn Sayyad was nearing puberty. He did not notice until the Prophet, peace and blessings be upon him, struck his back with his hand, then said: "Do you bear witness that I am the Messenger of Allah?" He looked at him and said: I bear witness that you are the Messenger of the unlettered! Ibn Sayyad said: Do you bear witness that I am the Messenger of Allah? The Prophet, peace and blessings be upon him, pressed him, then said: "I believe in Allah and His Messenger." Then he said to Ibn Sayyad: "What do you see?" Ibn Sayyad said: A truthful one and a liar come to me. The Prophet, peace and blessings be upon him, said: "The matter has been confused for you." The Prophet, peace and blessings be upon him, said: "I have concealed something for you." He said: It is ad-dukh. He said: "Be gone, for you will not go beyond your rank." Umar said: O Messenger of Allah! Do you permit me to strike his neck? The Prophet, peace and blessings be upon him, said: "If he is him, you will not be given power over him, and if he is not, then there is no good for you in killing him."
