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.
