The Book of Pilgrimage
15/61. Chapter:
Giving the meat, skin and blankets of the Hadi in charity; the butcher should not be given any of it; It is permissible to delegate someone else to offer the sacrifice
Sahih Muslim
وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا سُفْيَانُ، وَقَالَ، إِسْحَاقُ بْنُ إِبْرَاهِيمَ أَخْبَرَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ أَخْبَرَنِي أَبِي كِلاَهُمَا، عَنِ ابْنِ أَبِي نَجِيحٍ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ أَبِي، لَيْلَى عَنْ عَلِيٍّ، عَنِ النَّبِيِّ صلى الله عليه وسلم وَلَيْسَ فِي حَدِيثِهِمَا أَجْرُ الْجَازِرِ .
This hadith has been narrated on the authority of 'Ali (Allah be pleased with him) with another chain of transmitters, but there is no mention of the wages of the butcher in it.
