Messenger of Allah ﷺ and Ubai bin Kaʿb Al-Ansari went to the garden where Ibn Saiyad used to live. When Messenger of Allah ﷺ entered (the garden), he (i.e. Messenger of Allah ﷺ ) started hiding himself behind the date108 palms as he wanted to hear secretly the talk of Ibn Saiyad before the latter saw him. Ibn Saiyad wrapped with a soft decorated sheet was lying on his bed murmuring. Ibn Saiyad's mother saw the Prophet hiding behind the stems of the date-palms. She addressed Ibn Saiyad saying, "O Saf, this is Muhammad." Hearing that Ibn Saiyad stopped murmuring (or got cautious), the Prophet ﷺ said, "If she had left him undisturbed, he would have revealed his reality." (See Hadith No. 290, Vol 4 for details)  

سَمِعْتُ عَبْدَ اللَّهِ بْنَ عُمَرَ ؓ يَقُولُ انْطَلَقَ رَسُولُ اللَّهِ ﷺ وَأُبَىُّ بْنُ كَعْبٍ الأَنْصَارِيُّ يَؤُمَّانِ النَّخْلَ الَّتِي فِيهَا ابْنُ صَيَّادٍ حَتَّى إِذَا دَخَلَ رَسُولُ اللَّهِ ﷺ طَفِقَ رَسُولُ اللَّهِ ﷺ 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 ﷺ وَهْوَ يَتَّقِي بِجُذُوعِ النَّخْلِ فَقَالَتْ لاِبْنِ صَيَّادِ أَىْ صَافِ هَذَا مُحَمَّدٌ فَتَنَاهَى ابْنُ صَيَّادٍ قَالَ رَسُولُ اللَّهِ ﷺ لَوْ تَرَكَتْهُ بَيَّنَ  

ʿUmar bin Al-Khattab set out with Messenger of Allah 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 Messenger of Allah 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 Messenger of Allah 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." Messenger of Allah 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." ʿUmar said, "O Messenger of Allah ﷺ! Allow me to chop off h is neck." Allah's Apostle said (to ʿUmar). "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." ʿAbdullah bin ʿUmar added: Later on Messenger of Allah ﷺ and Ubai bin Kaʿb Al-Ansari (once again) went to the garden in which Ibn Saiyad was present. When Messenger of Allah 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." ʿAbdullah added: Messenger of Allah 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."

"The Messengers of Allah ﷺstood among the people,he praised Allah as is due to Him, then he mentioned the Dajjal and he said: 'Indeed I warn you of him. There has not been a Prophet except that he warned his people, and Nuh indeed warned his people – but I am to say something about him that no Prophet has said to his people: You should know that he is one-eyed, and Allah is certainly not one-eyed.'” Az-Zuhri said: “ ʿUmar bin Thabit Al-Ansari informed me that some of the Companions of the Prophet ﷺ informed him, that one day, the Prophet ﷺ was cautioning them against Fitnah and he said: 'You must know that not one of you will ever see his Lord until he dies. And indeed, he(the Dajjal) has “Kafir” written between his eyes; everyone who is averse to his behavior shall read it.'” (Sahih)

[Machine] Ibn Umar and Ubay ibn Ka'b went to the palm tree where Ibn Sayyad was. When they entered the palm tree, the Messenger of Allah ﷺ leaned against the trunk of the palm tree, fearing that Ibn Sayyad would hear something from him before seeing him. Ibn Sayyad was lying on his bed in Qatif, where there was a buzzing sound. His mother saw the Messenger of Allah ﷺ leaning against the trunk of the palm tree and said, "What is this noble man's name?" He said, "This is Muhammad." She became furious and said, "What a shame!" The Messenger of Allah ﷺ said, "If you left him alone between  

ابْنُ عُمَرَ انْطَلَقَ رَسُولُ اللهِ ﷺ وَأُبَىُّ بْنُ كَعْبٍ يَأْتِيَانِ النَّخْلَ الَّتِي فِيهَا ابْنُ صَيَّادٍ حَتَّى إِذَا دَخَلَا النَّخْلَ طَفِقَ رَسُولُ اللهِ ﷺ يَتَّقِي بِجُذُوعِ النَّخْلِ وَهُوَ يَخْتِلُ ابْنَ صَيَّادٍ أَنْ يَسْمَعَ مِنَ ابْنِ صَيَّادٍ شَيْئًا قَبْلَ أَنْ يَرَاهُ وَابْنُ صَيَّادٍ مُضْطَجِعٌ عَلَى فِرَاشِهِ فِي قَطِيفَةٍ لَهُ فِيهَا زَمْزَمَةٌ قَالَ فَرَأَتْ أُمُّهُ رَسُولَ اللهِ ﷺ وَهُوَ يَتَّقِي بِجُذُوعِ النَّخْلِ فَقَالَتْ أَيْ صَافِ وَهُوَ اسْمُهُ هَذَا مُحَمَّدٌ فَثَارَ فَقَالَ رَسُولُ اللهِ ﷺ لَوْ تَرَكَتْهُ بَيَّنَ  

[Machine] "And I heard Ibn Umar saying that after that, the Messenger of Allah ﷺ went with Ubayy ibn Ka'b to the date palm tree that belonged to Ibn Sayyad. When the Messenger of Allah ﷺ entered the date palm tree, he shook the trunks of the date palm tree and he loved to hear something from Ibn Sayyad before Ibn Sayyad could see him. But the Messenger of Allah ﷺ saw him lying, on a bed in a Qatifah that had a groaning noise coming from it. The mother of Ibn Sayyad saw the Messenger of Allah ﷺ shaking the trunks of the date palm tree and she said to Ibn Sayyad, and the Messenger of Allah ﷺ said, 'If you leave him.' Ibn Umar said that the Messenger of Allah ﷺ then ascended the pulpit and praised Allah as He deserves to be praised, and then he mentioned the Dajjal and said, 'I warn you about him. There was no Prophet who did not warn his people about him. Indeed, Noah warned his people about him. But I will tell you something about him that no Prophet told his people: learn that he is one-eyed and that Allah is not one-eyed.'"
