حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا هِشَامٌ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، أَخْبَرَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّهُ أَخْبَرَهُ أَنَّ عُمَرَ انْطَلَقَ فِي رَهْطٍ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم مَعَ النَّبِيِّ صلى الله عليه وسلم قِبَلَ ابْنِ صَيَّادٍ حَتَّى وَجَدُوهُ يَلْعَبُ مَعَ الْغِلْمَانِ عِنْدَ أُطُمِ بَنِي مَغَالَةَ، وَقَدْ قَارَبَ يَوْمَئِذٍ ابْنُ صَيَّادٍ يَحْتَلِمُ، فَلَمْ يَشْعُرْ حَتَّى ضَرَبَ النَّبِيُّ صلى الله عليه وسلم ظَهْرَهُ بِيَدِهِ ثُمَّ قَالَ النَّبِيُّ صلى الله عليه وسلم " أَتَشْهَدُ أَنِّي رَسُولُ اللَّهِ صلى الله عليه وسلم ". فَنَظَرَ إِلَيْهِ ابْنُ صَيَّادٍ فَقَالَ أَشْهَدُ أَنَّكَ رَسُولُ الأُمِّيِّينَ. فَقَالَ ابْنُ صَيَّادٍ لِلنَّبِيِّ صلى الله عليه وسلم أَتَشْهَدُ أَنِّي رَسُولُ اللَّهِ. قَالَ لَهُ النَّبِيُّ صلى الله عليه وسلم " آمَنْتُ بِاللَّهِ وَرُسُلِهِ " قَالَ النَّبِيُّ صلى الله عليه وسلم " مَاذَا تَرَى ". قَالَ ابْنُ صَيَّادٍ يَأْتِينِي صَادِقٌ وَكَاذِبٌ. قَالَ النَّبِيُّ صلى الله عليه وسلم " خُلِطَ عَلَيْكَ الأَمْرُ ". قَالَ النَّبِيُّ صلى الله عليه وسلم " إِنِّي قَدْ خَبَأْتُ لَكَ خَبِيئًا ". قَالَ ابْنُ صَيَّادٍ هُوَ الدُّخُّ. قَالَ النَّبِيُّ صلى الله عليه وسلم " اخْسَأْ فَلَنْ تَعْدُوَ قَدْرَكَ ". قَالَ عُمَرُ يَا رَسُولَ اللَّهِ، ائْذَنْ لِي فِيهِ أَضْرِبْ عُنُقَهُ. قَالَ النَّبِيُّ صلى الله عليه وسلم " إِنْ يَكُنْهُ فَلَنْ تُسَلَّطَ عَلَيْهِ، وَإِنْ لَمْ يَكُنْهُ فَلاَ خَيْرَ لَكَ فِي قَتْلِهِ ".
Umar and a group of the companions of the Prophet (ﷺ) set out with the Prophet to Ibn Saiyad. He found him playing with some boys near the hillocks of Bani Maghala. Ibn Saiyad at that time was nearing his puberty. He did not notice (the Prophet's presence) till the Prophet (ﷺ) stroked him on the back with his hand and said, "Ibn Saiyad! Do you testify that I am Allah's Messenger (ﷺ)?" Ibn Saiyad looked at him and said, "I testify that you are the Apostle of the illiterates." Then Ibn Saiyad asked the Prophet. "Do you testify that I am the apostle of Allah?" The Prophet (ﷺ) said to him, "I believe in Allah and His Apostles." Then the Prophet (ﷺ) said (to Ibn Saiyad). "What do you see?" Ibn Saiyad replied, "True people and false ones visit me." The Prophet said, "Your mind is confused as to this matter." The Prophet (ﷺ) added, " I have kept something (in my mind) for you." Ibn Saiyad said, "It is Ad-Dukh." The Prophet (ﷺ) said (to him), "Shame be on you! You cannot cross your limits." On that 'Umar said, "O Allah's Messenger (ﷺ)! Allow me to chop his head off." The Prophet (ﷺ) said, "If he should be him (i.e. Ad-Dajjal) then you cannot overpower him, and should he not be him, then you are not going to benefit by murdering him."
