The Book of Prayers (Kitab Al-Salat)

Muslim :: Book 4 : Hadith 2005

Abu Huraira reported Allah's Messenger (may peace be upon him) as saying: Did you not see when the man died and his eyes were fixedly open? He (Abu Huraira) said: Yes. He (the Holy Prophet) said: It is due to the fact that when (the soul leaves the body) his eyesight follows the soul.
