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.

حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، قَالَ حَدَّثَنَا زَيْدُ بْنُ حُبَابٍ، قَالَ أَخْبَرَنَا عَمْرُو بْنُ عُثْمَانَ بْنِ عَبْدِ الرَّحْمَنِ بْنِ سَعِيدِ بْنِ يَرْبُوعٍ الْمَخْزُومِيُّ، قَالَ حَدَّثَنِي جَدِّي، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ يَوْمَ فَتْحِ مَكَّةَ " أَرْبَعَةٌ لاَ أُؤْمِنُهُمْ فِي حِلٍّ وَلاَ حَرَمٍ " . فَسَمَّاهُمْ . قَالَ وَقَيْنَتَيْنِ كَانَتَا لِمِقْيَسٍ فَقُتِلَتْ إِحْدَاهُمَا وَأُفْلِتَتِ الأُخْرَى فَأَسْلَمَتْ . قَالَ أَبُو دَاوُدَ لَمْ أَفْهَمْ إِسْنَادَهُ مِنِ ابْنِ الْعَلاَءِ كَمَا أُحِبُّ .
