Abu Dawud Book 8, Hadith Number 2678.

Narated By Sa’id ibn Yarbu’ al-Makhzumi : The Prophet (PBUH) said: on the day of the conquest of Mecca: There are four persons whom I shall not give protection in the sacred and non-sacred territory. He then named them. There were two singing girls of al-Maqis; one of them was killed and the other escaped and embraced Islam.
