Sayyiduna Abu Hurayrah (may Allah be pleased with him) says: The people mentioned a man before the Prophet (peace and blessings be upon him) (the narrator is unsure; perhaps the words are:) a man said: "O Messenger of Allah! So-and-so stays asleep until morning; he does not pray until morning comes." The Prophet (peace and blessings be upon him) said: "Satan has urinated in his ear." Hasan al-Basri says: By Allah! His urine is heavy.
This narration was recorded by Imam Ahmad, and its narrators are the narrators of the "Sahih".
