Narrated Sa'id ibn Yarbu' al-Makhzumi:

The Prophet (ﷺ) 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. Abu Dawud said: I could not understand its chain of narrators from Ibn al-'Ala' as I liked.
