Narrated 'Abdullah bin Umar (ra): Once, Allah's Messenger (saws) accompanied by Ubai bin Ka'b set out to Ibn Saiyyad. He was informed that Ibn Saiyyad was in a garden of date palms. When Allah's Messenger (saws) entered the garden of date-palms, he started hiding himself behind the trunks of the palms while Ibn Saiyyad was covered with a velvet sheet with murmurs emanating from under it. Ibn Saiyyah's mother saw Allah's Messenger (saws) and said, O Saf! This is Muhammad. So Ibn Saiyyad got up. Allah's Messenger (saws) said, If she had left him (in his state), the truth would have been clear.
