Sahih al-bukhari:3056 Chapter: The superiority of Jihad Book 56, Hadith 262

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 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.”
