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  

(Later on) Messenger of Allah 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 the 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."  

انْطَلَقَ النَّبِيُّ ﷺ وَأُبَىُّ بْنُ كَعْبٍ يَأْتِيَانِ النَّخْلَ الَّذِي فِيهِ ابْنُ صَيَّادٍ حَتَّى إِذَا دَخَلَ النَّخْلَ طَفِقَ النَّبِيُّ ﷺ 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 ﷺ وَهْوَ يَتَّقِي بِجُذُوعِ النَّخْلِ فَقَالَتْ لاِبْنِ صَيَّادٍ أَىْ صَافِ وَهْوَ اسْمُهُ فَثَارَ ابْنُ صَيَّادٍ فَقَالَ النَّبِيُّ ﷺ لَوْ تَرَكَتْهُ بَيَّنَ وَقَالَ سَالِمٌ قَالَ ابْنُ عُمَرَ ثُمَّ قَامَ النَّبِيُّ ﷺ 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  

"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)  

قَامَ رَسُولُ اللَّهِ ﷺ فِي النَّاسِ فَأَثْنَى عَلَى اللَّهِ بِمَا هُوَ أَهْلُهُ ثُمَّ ذَكَرَ الدَّجَّالَ فَقَالَ إِنِّي لأُنْذِرُكُمُوهُ وَمَا مِنْ نَبِيٍّ إِلاَّ وَقَدْ أَنْذَرَ قَوْمَهُ وَلَقَدْ أَنْذَرَهُ نُوحٌ قَوْمَهُ وَلَكِنِّي سَأَقُولُ لَكُمْ فِيهِ قَوْلاً لَمْ يَقُلْهُ نَبِيٌّ لِقَوْمِهِ تَعْلَمُونَ أَنَّهُ أَعْوَرُ وَإِنَّ اللَّهَ لَيْسَ بِأَعْوَرَ قَالَ الزُّهْرِيُّ وَأَخْبَرَنِي عُمَرُ بْنُ ثَابِتٍ الأَنْصَارِيُّ أَنَّهُ أَخْبَرَهُ بَعْضُ أَصْحَابِ النَّبِيِّ ﷺ أَنَّ النَّبِيَّ ﷺ قَالَ يَوْمَئِذٍ لِلنَّاسِ وَهُوَ يُحَذِّرُهُمْ فِتْنَتَهُ تَعْلَمُونَ أَنَّهُ لَنْ يَرَى أَحَدٌ مِنْكُمْ رَبَّهُ حَتَّى يَمُوتَ وَإِنَّهُ مَكْتُوبٌ بَيْنَ عَيْنَيْهِ ك ف ر يَقْرَأُهُ مَنْ كَرِهَ عَمَلَهُ  

[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
