It was narrated that `Abdullah said:

We were walking with the Prophet (ﷺ) and he passed by Ibn Sayyad and said: "I am hiding something in my mind for you.” Ibn Sayyad said: (It is) dukh (referring to Soorat ad-Dukhan). The Messenger of Allah (ﷺ) said. "May you be disgraced and dishonoured; you will never go beyond your station." ‘Umar said: O Messenger of Allah, let me strike his neck. He said: “No, If he is the one you fear he is, you will never be able to kill him."
