Ibn Umar said: The prophet صلی اللہ علیہ وسلم passed by Ibn Saeed along with some of his companions. Umar bin al-Kattab was among them. He was playing with boys near the fortress of Banu Maghalah. He was near the age of puberty (i. e. a boy). Before he was aware, the Messenger of Allah صلی اللہ علیہ وسلم gave him a pat on the back and said: Do you testify that you are the Messenger of Allah Ibn Sayyad then looked at him and said: I testify that you are the Messenger of Gentiles. Ibn Sayyad then said the prophet صلی اللہ علیہ وسلم then asked him: What comes to you ? He replied: One who speaks the truth and one who lies come to me. The prophet (may peace upon him) said: You are confused. The Messenger of Allah (may peace upon him) said to him: I have concealed something (in my hand) and he concealed the verse “the day when the sky will bring forth smoke (dukhan) clearly visible Ibn Sayyad said: It is smoke (dukhan). The Messenger of Allah صلی اللہ علیہ وسلم said: Away with you, You cannot get farther than your rank. Umar said: “Messenger of Allah, permit me to cut off his head. The Messenger of Allah صلی اللہ علیہ وسلم said: If he is the one (the Dajjal), you will not be given power over him, and if he is not, you will not do well in killing him.
