Sayyiduna Ibn Abbas (may Allah be pleased with them both) says that I went to visit my maternal aunt and I coincided with the night of the Messenger of Allah (peace be upon him) (meaning that this night the Prophet (peace be upon him) was at my aunt's house). Then he narrated the hadith further and said that the Messenger of Allah (peace be upon him) prayed two rak'ahs (Sunnah), then he lay down until I heard his snoring. Then the iqamah for prayer was given, and the Prophet (peace be upon him) went out and led the prayer.
