صَحِيحُ مُسْلِمٍ
Sahih Muslim 1659 e
The Book of Oaths
Treatment of slaves, and the expiation of one who slaps his slave
وَحَدَّثَنِيهِ بِشْرُ بْنُ خَالِدٍ، أَخْبَرَنَا مُحَمَّدٌ، - يَعْنِي ابْنَ جَعْفَرٍ - عَنْ شُعْبَةَ، بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ قَوْلَهُ أَعُوذُ بِاللَّهِ أَعُوذُ بِرَسُولِ اللَّهِ صلى الله عليه وسلم .
This hadith has been narrated on the authority of Shu'ba with the same chain of transmitters, but made no mention of (these words) of his: I seek refuge with Allah, I seek refuge with Allah's Messenger (ﷺ).
