Narrated Nafi`:
حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ ، حَدَّثَنَا أَنَسُ بْنُ عِيَاضٍ ، حَدَّثَنَا مُوسَى بْنُ عُقْبَةَ ، عَنْ نَافِعٍ ، أَنَّ ابْنَ عُمَرَ ـ رضى الله عنهما ـ كَانَ يَبْعَثُ بِهَدْيِهِ مِنْ جَمْعٍ مِنْ آخِرِ اللَّيْلِ، حَتَّى يُدْخَلَ بِهِ مَنْحَرُ النَّبِيِّ صلى الله عليه وسلم مَعَ حُجَّاجٍ فِيهِمُ الْحُرُّ وَالْمَمْلُوكُ.
Ibn `Umar used to send his Hadi from Jam' (to Mina) in the last third of the night with the pilgrims amongst whom there were free men and slaves, till it was taken into the Manhar (slaughtering place) of the Prophet (ﷺ) .
