Yahya related to me from Malik, from Ibn Shihab, from Ubaydullah
ibn Abdullah ibn Utba ibn Masud, from Abdullah ibn Abbas, that as-Sab
ibn Jaththama al-Laythi once gave a wild ass to the Messenger of
Allah, may Allah bless him and grant him peace, while he was at al-
Abwa, or Waddan, and the Messenger of Allah, may Allah bless him and
grant him peace, gave it back to him. However, when the Messenger of
Allah, may Allah bless him and grant him peace, saw the expression on
the man's face he said, "We only gave it back to you because we are in
ihram."
Muwatta Malik Book 20, Hadith 85
