abudawud:1728Naṣr b. ʿAlī > Abū Aḥmad > Sufyān > ʿUbaydullāh > Nāfiʿ

Ibn ʿUmr used to seat his slave girl called Safiyyah behind him(on the Camel) and thus she travelled to Makkah in his company.  

أبو داود:١٧٢٨حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ حَدَّثَنَا أَبُو أَحْمَدَ حَدَّثَنَا سُفْيَانُ عَنْ عُبَيْدِ اللَّهِ عَنْ نَافِعٍ أَنَّ ابْنَ عُمَرَ كَانَ يُرْدِفُ مَوْلاَةً لَهُ

يُقَالُ لَهَا صَفِيَّةُ تُسَافِرُ مَعَهُ إِلَى مَكَّةَ
