Sahih Muslim 2930 a, 2931, 169 d
'Abdullah b. Umar reported:
'Umar b. Khattab went along with Allah's Messenger (ﷺ) in the company of some persons to Ibn Sayyad that he found him playing with children near the battlement of Bani Maghala and Ibn Sayyad was at that time just at the threshold of adolescence and he did not perceive (the presence of Holy Prophet) until Allah's Messenger (ﷺ) struck his back with his hands. Allah's Messenger (ﷺ) said: Ibn Sayyad, don't you bear witness that I am the messenger of Allah? Ibn Sayyad looked toward him and he said: I bear witness to the fact that you the messenger of the unlettered. Ibn Sayyad said to the Allah's Messenger (ﷺ): Do you bear witness to the fact that I am the messenger of Allah? Allah's Messenger (ﷺ) rejected this and said: I affirm my faith in Allah and in His messengers. Then Allah's Messenger (ﷺ) said to him: What do you see? Ibn Sayyad said: It is a Dukh. Thereupon Allah's Messenger (ﷺ) said: May you be disgraced and dishonoured, you would not not be able to go beyond your rank. 'Umar b. Khattab said: Allah's Messenger, permit me that I should strike his neck. Thereupon Allah's Messenger (ﷺ) said: If he is the same (Dajjal) who would appear near the Last Hour, you would not be able to overpower him, and if he is not that there is no good for you to kill him. 'Abdullah b. 'Umar further narrated that after some time Allah's Messenger (ﷺ) and Ubayy b. Ka'b went towards the palm trees where Ibn Sayyad was. When Allah's Messenger (ﷺ) went near the tree he hid himself behind a tree with the intention of hearing something from Ibn sayyad before Ibn Sayyad could see him, but Allah's Messenger (ﷺ) saw him on a bed with a blanket around him from which a murmuring sound was being heard and Ibn Sayyad's mother saw Allah's Messenger (ﷺ) behind the trunk of the palm tree. She said to Ibn Sayyad: Saf (that being his name), here is Muhammad. Thereupon Ibn Sayyad jumped up murmuring and Allah's Messenger (ﷺ) said: If she had left him alone he would have made things clear. Abdullah b. Umar told that Allah's Messenger (ﷺ) stood up amongst the people and lauded Allah as He deserved, then he made a mention of the Dajjal and said: I warn you of him and there is no Prophet who has not warned his people against the Dajjal. Even Noah warned (against him) but I am going to tell you a thing which no Prophet told his people. You must know that he (the Dajjal) is one-eyed and Allah, the Exalted and Glorious, is not one-eyed. Ibn Shihab said: 'Umar b. Thabit al-Ansari informed me that some of the Companions of Allah's Messenger (ﷺ) informed him that the day when Allah's Messenger (ﷺ) warned people against the Dajjal, he also said: There would be written between his two eyes (the word) Kafir (infidel) and everyone who would resent his deeds would be able to read or every Muslim would be about to read, and he also said: Bear this thing in mind that none amongst you would be able to see Allah, the Exalted and Glorious, until he dies.
حَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى بْنِ عَبْدِ اللَّهِ بْنِ حَرْمَلَةَ بْنِ عِمْرَانَ التُّجِيبِيُّ، أَخْبَرَنِي ابْنُ،
 وَهْبٍ أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، أَخْبَرَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ
 أَخْبَرَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ انْطَلَقَ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي رَهْطٍ قِبَلَ ابْنِ
 صَيَّادٍ حَتَّى وَجَدَهُ يَلْعَبُ مَعَ الصِّبْيَانِ عِنْدَ أُطُمِ بَنِي مَغَالَةَ وَقَدْ قَارَبَ ابْنُ صَيَّادٍ يَوْمَئِذٍ الْحُلُمَ
 فَلَمْ يَشْعُرْ حَتَّى ضَرَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم ظَهْرَهُ بِيَدِهِ ثُمَّ قَالَ رَسُولُ اللَّهِ
 صلى الله عليه وسلم لاِبْنِ صَيَّادٍ ‏"‏ أَتَشْهَدُ أَنِّي رَسُولُ اللَّهِ ‏"‏ ‏.‏ فَنَظَرَ إِلَيْهِ ابْنُ صَيَّادٍ فَقَالَ
 أَشْهَدُ أَنَّكَ رَسُولُ الأُمِّيِّينَ ‏.‏ فَقَالَ ابْنُ صَيَّادٍ لِرَسُولِ اللَّهِ صلى الله عليه وسلم أَتَشْهَدُ أَنِّي
 رَسُولُ اللَّهِ فَرَفَضَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم وَقَالَ ‏"‏ آمَنْتُ بِاللَّهِ وَبِرُسُلِهِ ‏"‏ ‏.‏ ثُمَّ
 قَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَاذَا تَرَى ‏"‏ ‏.‏ قَالَ ابْنُ صَيَّادٍ يَأْتِينِي صَادِقٌ
 وَكَاذِبٌ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ خُلِّطَ عَلَيْكَ الأَمْرُ ‏"‏ ‏.‏ ثُمَّ قَالَ لَهُ رَسُولُ
 اللَّهِ صلى الله عليه وسلم ‏"‏ إِنِّي قَدْ خَبَأْتُ لَكَ خَبِيئًا ‏"‏ ‏.‏ فَقَالَ ابْنُ صَيَّادٍ ‏"‏ هُوَ الدُّخُّ ‏"‏
 ‏.‏ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ اخْسَأْ فَلَنْ تَعْدُوَ قَدْرَكَ ‏"‏ ‏.‏ فَقَالَ عُمَرُ بْنُ
 الْخَطَّابِ ذَرْنِي يَا رَسُولَ اللَّهِ أَضْرِبْ عُنُقَهُ ‏.‏ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏
 إِنْ يَكُنْهُ فَلَنْ تُسَلَّطَ عَلَيْهِ وَإِنْ لَمْ يَكُنْهُ فَلاَ خَيْرَ لَكَ فِي قَتْلِهِ ‏"‏ ‏.‏ 
 
 وَقَالَ سَالِمُ بْنُ عَبْدِ اللَّهِ سَمِعْتُ عَبْدَ اللَّهِ بْنَ عُمَرَ، يَقُولُ انْطَلَقَ بَعْدَ ذَلِكَ رَسُولُ
 اللَّهِ صلى الله عليه وسلم وَأُبَىُّ بْنُ كَعْبٍ الأَنْصَارِيُّ إِلَى النَّخْلِ الَّتِي فِيهَا ابْنُ صَيَّادٍ حَتَّى
 إِذَا دَخَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم النَّخْلَ طَفِقَ يَتَّقِي بِجُذُوعِ النَّخْلِ وَهُوَ يَخْتِلُ أَنْ
 يَسْمَعَ مِنِ ابْنِ صَيَّادٍ شَيْئًا قَبْلَ أَنْ يَرَاهُ ابْنُ صَيَّادٍ فَرَآهُ رَسُولُ اللَّهِ صلى الله عليه وسلم
 وَهُوَ مُضْطَجِعٌ عَلَى فِرَاشٍ فِي قَطِيفَةٍ لَهُ فِيهَا زَمْزَمَةٌ فَرَأَتْ أُمُّ ابْنِ صَيَّادٍ رَسُولَ اللَّهِ صلى
 الله عليه وسلم وَهُوَ يَتَّقِي بِجُذُوعِ النَّخْلِ فَقَالَتْ لاِبْنِ صَيَّادٍ يَا صَافِ - وَهُوَ اسْمُ ابْنِ صَيَّادٍ
 - هَذَا مُحَمَّدٌ ‏.‏ فَثَارَ ابْنُ صَيَّادٍ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لَوْ تَرَكَتْهُ بَيَّنَ
 ‏"‏ ‏.‏ 
 
 قَالَ سَالِمٌ قَالَ عَبْدُ اللَّهِ بْنُ عُمَرَ فَقَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي النَّاسِ
 فَأَثْنَى عَلَى اللَّهِ بِمَا هُوَ أَهْلُهُ ثُمَّ ذَكَرَ الدَّجَّالَ فَقَالَ ‏"‏ إِنِّي لأُنْذِرُكُمُوهُ مَا مِنْ نَبِيٍّ إِلاَّ وَقَدْ
 أَنْذَرَهُ قَوْمَهُ لَقَدْ أَنْذَرَهُ نُوحٌ قَوْمَهُ وَلَكِنْ أَقُولُ لَكُمْ فِيهِ قَوْلاً لَمْ يَقُلْهُ نَبِيٌّ لِقَوْمِهِ تَعَلَّمُوا أَنَّهُ
 أَعْوَرُ وَأَنَّ اللَّهَ تَبَارَكَ وَتَعَالَى لَيْسَ بِأَعْوَرَ ‏"‏ ‏.‏ قَالَ ابْنُ شِهَابٍ وَأَخْبَرَنِي عُمَرُ بْنُ ثَابِتٍ
 الأَنْصَارِيُّ أَنَّهُ أَخْبَرَهُ بَعْضُ أَصْحَابِ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّ رَسُولَ اللَّهِ صلى
 الله عليه وسلم قَالَ يَوْمَ حَذَّرَ النَّاسَ الدَّجَّالَ ‏"‏ إِنَّهُ مَكْتُوبٌ بَيْنَ عَيْنَيْهِ كَافِرٌ يَقْرَؤُهُ مَنْ
 كَرِهَ عَمَلَهُ أَوْ يَقْرَؤُهُ كُلُّ مُؤْمِنٍ ‏"‏ ‏.‏ وَقَالَ ‏"‏ تَعَلَّمُوا أَنَّهُ لَنْ يَرَى أَحَدٌ مِنْكُمْ رَبَّهُ عَزَّ وَجَلَّ
 حَتَّى يَمُوتَ ‏"‏ ‏.‏
