Sahih al-Bukhari 6173-6175
Narrated `Abdullah bin `Umar:
`Umar bin Al-Khattab set out with Allah's Messenger (ﷺ), and a group of his companions to Ibn Saiyad. 
They found him playing with the boys in the fort or near the Hillocks of Bani Maghala. Ibn Saiyad 
was nearing his puberty at that time, and he did not notice the arrival of the Prophet (ﷺ) till Allah's 
Apostle stroked him on the back with his hand and said, "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 unlettered ones 
(illiterates)". Then Ibn Saiyad said to the Prophets . "Do you testify that I am Allah's Messenger (ﷺ)?" The 
Prophet denied that, saying, "I believe in Allah and all His Apostles," and then said to Ibn Saiyad, 
"What do you see?" Ibn Saiyad said, "True people and liars visit me." The Prophet (ﷺ) said, "You have 
been confused as to this matter." Allah's Messenger (ﷺ) added, "I have kept something for you (in my 
mind)." Ibn Saiyad said, "Ad-Dukh." The Prophet (ﷺ) said, "Ikhsa (you should be ashamed) for you can 
not cross your limits." `Umar said, "O Allah's Messenger (ﷺ)! Allow me to chop off h is neck." Allah's 
Apostle said (to `Umar). "Should this person be him (i.e. Ad-Dajjal) then you cannot over-power him; 
and should he be someone else, then it will be no use your killing him." `Abdullah bin `Umar added: 
Later on Allah's Messenger (ﷺ) and Ubai bin Ka`b Al-Ansari (once again) went to the garden in which Ibn 
Saiyad was present. 
When Allah's Messenger (ﷺ) entered the garden, he started hiding behind the trunks of the date-palms 
intending to hear something from Ibn Saiyad before the latter could see him. Ibn Saiyad was Lying on 
his bed, covered with a velvet sheet from where his mumur were heard. Ibn Saiyad's mother saw the 
Prophet and said, "O Saf (the nickname of Ibn Saiyad)! Here is Muhammad!" Ibn Saiyad stopped his 
murmuring. The Prophet (ﷺ) said, "If his mother had kept quiet, then I would have learnt more about 
him." `Abdullah added: Allah's Messenger (ﷺ) stood up before the people (delivering a sermon), and after 
praising and glorifying Allah as He deserved, he mentioned the Ad-Dajjal saying, "I warn you against 
him, and there has been no prophet but warned his followers against him. Noah warned his followers 
against him but I am telling you about him, something which no prophet has told his people of, and 
that is: Know that he is blind in one eye where as Allah is not so."
حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، أَخْبَرَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ انْطَلَقَ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي رَهْطٍ مِنْ أَصْحَابِهِ قِبَلَ ابْنِ صَيَّادٍ، حَتَّى وَجَدَهُ يَلْعَبُ مَعَ الْغِلْمَانِ فِي أُطُمِ بَنِي مَغَالَةَ، وَقَدْ قَارَبَ ابْنُ صَيَّادٍ يَوْمَئِذٍ الْحُلُمَ، فَلَمْ يَشْعُرْ حَتَّى ضَرَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم ظَهْرَهُ بِيَدِهِ ثُمَّ قَالَ ‏"‏ أَتَشْهَدُ أَنِّي رَسُولُ اللَّهِ ‏"‏‏.‏ فَنَظَرَ إِلَيْهِ فَقَالَ أَشْهَدُ أَنَّكَ رَسُولُ الأُمِّيِّينَ‏.‏ ثُمَّ قَالَ ابْنُ صَيَّادٍ أَتَشْهَدُ أَنِّي رَسُولُ اللَّهِ فَرَضَّهُ النَّبِيُّ صلى الله عليه وسلم ثُمَّ قَالَ ‏"‏ آمَنْتُ بِاللَّهِ وَرُسُلِهِ ‏"‏‏.‏ ثُمَّ قَالَ لاِبْنِ صَيَّادٍ ‏"‏ مَاذَا تَرَى ‏"‏‏.‏ قَالَ يَأْتِينِي صَادِقٌ وَكَاذِبٌ‏.‏ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ خُلِّطَ عَلَيْكَ الأَمْرُ ‏"‏‏.‏ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنِّي خَبَأْتُ لَكَ خَبِيئًا ‏"‏‏.‏ قَالَ هُوَ الدُّخُّ‏.‏ قَالَ ‏"‏ اخْسَأْ، فَلَنْ تَعْدُوَ قَدْرَكَ ‏"‏‏.‏ قَالَ عُمَرُ يَا رَسُولَ اللَّهِ أَتَأْذَنُ لِي فِيهِ أَضْرِبْ عُنُقَهُ‏.‏ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنْ يَكُنْ هُوَ لاَ تُسَلَّطُ عَلَيْهِ، وَإِنْ لَمْ يَكُنْ هُوَ فَلاَ خَيْرَ لَكَ فِي قَتْلِهِ ‏"‏‏.‏ قَالَ سَالِمٌ فَسَمِعْتُ عَبْدَ اللَّهِ بْنَ عُمَرَ، يَقُولُ انْطَلَقَ بَعْدَ ذَلِكَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأُبَىُّ بْنُ كَعْبٍ الأَنْصَارِيُّ يَؤُمَّانِ النَّخْلَ الَّتِي فِيهَا ابْنُ صَيَّادٍ، حَتَّى إِذَا دَخَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم طَفِقَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَتَّقِي بِجُذُوعِ النَّخْلِ، وَهْوَ يَخْتِلُ أَنْ يَسْمَعَ مِنِ ابْنِ صَيَّادٍ شَيْئًا قَبْلَ أَنْ يَرَاهُ، وَابْنُ صَيَّادٍ مُضْطَجِعٌ عَلَى فِرَاشِهِ فِي قَطِيفَةٍ لَهُ فِيهَا رَمْرَمَةٌ أَوْ زَمْزَمَةٌ، فَرَأَتْ أُمُّ ابْنِ صَيَّادٍ النَّبِيَّ صلى الله عليه وسلم وَهْوَ يَتَّقِي بِجُذُوعِ النَّخْلِ، فَقَالَتْ لاِبْنِ صَيَّادٍ أَىْ صَافِ ـ وَهْوَ اسْمُهُ ـ هَذَا مُحَمَّدٌ‏.‏ فَتَنَاهَى ابْنُ صَيَّادٍ‏.‏ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لَوْ تَرَكَتْهُ بَيَّنَ ‏"‏‏.‏ قَالَ سَالِمٌ قَالَ عَبْدُ اللَّهِ قَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي النَّاسِ فَأَثْنَى عَلَى اللَّهِ بِمَا هُوَ أَهْلُهُ، ثُمَّ ذَكَرَ الدَّجَّالَ فَقَالَ ‏"‏ إِنِّي أُنْذِرُكُمُوهُ، وَمَا مِنْ نَبِيٍّ إِلاَّ وَقَدْ أَنْذَرَ قَوْمَهُ، لَقَدْ أَنْذَرَهُ نُوحٌ قَوْمَهُ، وَلَكِنِّي سَأَقُولُ لَكُمْ فِيهِ قَوْلاً لَمْ يَقُلْهُ نَبِيٌّ لِقَوْمِهِ، تَعْلَمُونَ أَنَّهُ أَعْوَرُ، وَأَنَّ اللَّهَ لَيْسَ بِأَعْوَرَ ‏"‏‏.
