Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) used to come to the house of Sayyidah Umm Sulaym (may Allah be pleased with her) and sleep on her bedding, and his sleep was deep. After this the narrator recorded the complete hadith.
Imam Abu Ya'la recorded it, and its narrators are the narrators of the "Sahih".
