Narrated `Abdullah bin `Umar: Allah's Apostle and Ubai bin Ka`b Al-Ansari went to the garden where Ibn Saiyad used to live. When Allah's Apostle entered (the garden), he (i.e. Allah's Apostle ) 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 said, "If she had left him undisturbed, he would have revealed his reality." (See Hadith No. 290, Vol 4 for details)

(Ibn `Umar added): Later on Allah's Apostle (p.b.u.h) once again went along with Ubai bin Ka`b to the date-palm trees (garden) where Ibn Saiyad was staying. The Prophet (p.b.u.h) wanted to hear something from Ibn Saiyad before Ibn Saiyad could see him, and the Prophet (p.b.u.h) saw him lying covered with a sheet and from where his murmurs were heard. Ibn Saiyad's mother saw Allah's Apostle while he was hiding himself behind the trunks of the date-palm trees. She addressed Ibn Saiyad, "O Saf ! (and this was the name of Ibn Saiyad) Here is Muhammad." And with that Ibn Saiyad got up. The Prophet said, "Had this woman left him (Had she not disturbed him), then Ibn Saiyad would have revealed the reality of his case.

Narrated Ibn 'Umar: Umar and a group of the companions of the Prophet set out with the Prophet to Ibn Saiyad. He found him playing with some boys near the hillocks of Bani Maghala. Ibn Saiyad at that time was nearing his puberty. He did not notice (the Prophet's presence) till the Prophet stroked him on the back with his hand and said, "Ibn Saiyad! Do you testify that I am Allah's Apostle?" Ibn Saiyad looked at him and said, "I testify that you are the Apostle of the illiterates." Then Ibn Saiyad asked the Prophet. "Do you testify that I am the apostle of Allah?" The Prophet said to him, "I believe in Allah and His Apostles." Then the Prophet said (to Ibn Saiyad). "What do you see?" Ibn Saiyad replied, "True people and false ones visit me." The Prophet said, "Your mind is confused as to this matter." The Prophet added, " I have kept something (in my mind) for you." Ibn Saiyad said, "It is Ad-Dukh." The Prophet said (to him), "Shame be on you! You cannot cross your limits." On that 'Umar said, "O Allah's Apostle! Allow me to chop his head off." The Prophet said, "If he should be him (i.e. Ad-Dajjal) then you cannot overpower him, and should he not be him, then you are not going to benefit by murdering him."

Narrated Ibn Umar: (Later on) Allah's Apostle (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 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 said, "Had this woman let him to himself, he would have revealed the reality of his case."

Narrated Ibn `Abbas: Allah's Apostle said to Ibn Saiyad "I have hidden something for you in my mind; What is it?" He said, "Ad-Dukh." The Prophet said, "Ikhsa."

Narrated `Abdullah bin `Umar: `Umar bin Al-Khattab set out with Allah's Apostle, 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 till Allah's Apostle stroked him on the back with his hand and said, "Do you testify that I am Allah's Apostle?" 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 Apostle?" 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 said, "You have been confused as to this matter." Allah's Apostle added, "I have kept something for you (in my mind)." Ibn Saiyad said, "Ad-Dukh." The Prophet said, "Ikhsa (you should be ashamed) for you can not cross your limits." `Umar said, "O Allah's Apostle! 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."

Narrated Ibn `Umar: The Prophet said to Ibn Saiyad, "I have kept for you a secret." Ibn Saiyad said, "Ad-Dukh." The Prophet said, "Keep quiet, for you cannot go beyond your limits (or you cannot exceed what has been foreordained for you)." On that, `Umar said (to the Prophet ), "Allow me to chop off his neck!" The Prophet said, "Leave him, for if he is he (i.e., Ad-Dajjal), then you will not be able to overcome him, and if he is not, then you gain no good by killing him."
