قَالَ ابْنُ عُمَرَ انْطَلَقَ النَّبِيُّ صلى الله عليه وسلم وَأُبَىُّ بْنُ كَعْبٍ يَأْتِيَانِ النَّخْلَ الَّذِي فِيهِ ابْنُ صَيَّادٍ، حَتَّى إِذَا دَخَلَ النَّخْلَ طَفِقَ النَّبِيُّ صلى الله عليه وسلم يَتَّقِي بِجُذُوعِ النَّخْلِ وَهْوَ يَخْتِلُ ابْنَ صَيَّادٍ أَنْ يَسْمَعَ مِنِ ابْنِ صَيَّادٍ شَيْئًا قَبْلَ أَنْ يَرَاهُ، وَابْنُ صَيَّادٍ مُضْطَجِعٌ عَلَى فِرَاشِهِ فِي قَطِيفَةٍ لَهُ فِيهَا رَمْزَةٌ، فَرَأَتْ أُمُّ ابْنِ صَيَّادٍ النَّبِيَّ صلى الله عليه وسلم وَهْوَ يَتَّقِي بِجُذُوعِ النَّخْلِ، فَقَالَتْ لاِبْنِ صَيَّادٍ أَىْ صَافِ ـ وَهْوَ اسْمُهُ ـ فَثَارَ ابْنُ صَيَّادٍ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ لَوْ تَرَكَتْهُ بَيَّنَ ‏"‏‏.‏ وَقَالَ سَالِمٌ قَالَ ابْنُ عُمَرَ ثُمَّ قَامَ النَّبِيُّ صلى الله عليه وسلم فِي النَّاسِ فَأَثْنَى عَلَى اللَّهِ بِمَا هُوَ أَهْلُهُ، ثُمَّ ذَكَرَ الدَّجَّالَ فَقَالَ ‏"‏ إِنِّي أُنْذِرُكُمُوهُ، وَمَا مِنْ نَبِيٍّ إِلاَّ قَدْ أَنْذَرَهُ قَوْمَهُ، لَقَدْ أَنْذَرَهُ نُوحٌ قَوْمَهُ، وَلَكِنْ سَأَقُولُ لَكُمْ فِيهِ قَوْلاً لَمْ يَقُلْهُ نَبِيٌّ لِقَوْمِهِ، تَعْلَمُونَ أَنَّهُ أَعْوَرُ وَأَنَّ اللَّهَ لَيْسَ بِأَعْوَرَ ‏"‏‏.‏

Narrated Ibn Umar: (Later on) Allah's Messenger (ﷺ) (once again) went along with Ubai bin Ka'b to the garden of date-palms where Ibn Saiyad was staying. When the Prophet entered the garden, he started hiding himself behind the trunks of the date-palms as he wanted to hear something from Ibn Saiyad before the latter could see him. Ibn Saiyad was lying in his bed, covered with a velvet sheet from where his murmurs were heard. Ibn Saiyad's mother saw the Prophet (ﷺ) while he was hiding himself behind the trunks of the date-palms. She addressed Ibn Saiyad, "O Saf!" (And this was his name). Ibn Saiyad got up. The Prophet (ﷺ) said, "Had this woman let him to himself, he would have revealed the reality of his case." Then the Prophet (ﷺ) got up amongst the people, glorifying Allah as He deserves, he mentioned Ad-Dajjal, saying, "I warn you about him (i.e. Ad-Dajjal) and there is no prophet who did not warn his nation about him, and Noah warned his nation about him, but I tell you a statement which no prophet informed his nation of. You should understand that he is a one-eyed man and Allah is not one-eyed
