This tradition has been narrated by Dawud b. Sawar al-Muzani through a different chain of transmitters and to the same effect. This version adds; if any of you marries his slave-girl to his male-slave or his servant, he should not look at her private part below her navel and above her knees.

Abu Dawud said:

Waki' misunderstood the name of Dawud b. Sawar. Abu Dawud al-Tayalisi has narrated this tradition from him. He said: Anu Hamzah Sawar al-Sairafi.

حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنِي دَاوُدُ بْنُ سَوَّارٍ الْمُزَنِيُّ، بِإِسْنَادِهِ وَمَعْنَاهُ وَزَادَ
" وَإِذَا زَوَّجَ أَحَدُكُمْ خَادِمَهُ عَبْدَهُ أَوْ أَجِيرَهُ فَلاَ يَنْظُرْ إِلَى مَا دُونَ السُّرَّةِ وَفَوْقَ الرُّكْبَةِ " . قَالَ أَبُو دَاوُدَ وَهِمَ وَكِيعٌ فِي اسْمِهِ وَرَوَى عَنْهُ أَبُو دَاوُدَ الطَّيَالِسِيُّ هَذَا الْحَدِيثَ فَقَالَ حَدَّثَنَا أَبُو حَمْزَةَ سَوَّارٌ الصَّيْرَفِيُّ .
