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
Translation
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

And if any of you marries off his servant, his slave, or his employee, let him not look at what is below the navel and above the knee.

Abu Dawud said: Waki' was mistaken regarding his name. Abu Dawud al-Tayalisi narrated this hadith from him and said: Abu Hamzah Sawar al-Sayrafi narrated to us.
