The Book of Pilgrimage
(64)
Chapter: It is recommended to send the sacrificial animal to the Haram for one who does not intend to go there himself; It is reommended to garland it and to make the garland, but the one who sends it does not enter a state of Ihram, and nothing is forbidden to him because of that
(64)
باب اسْتِحْبَابِ بَعْثِ الْهَدْىِ إِلَى الْحَرَمِ لِمَنْ لاَ يُرِيدُ الذَّهَابَ بِنَفْسِهِ وَاسْتِحْبَابِ تَقْلِيدِهِ وَفَتْلِ الْقَلاَئِدِ وَأَنَّ بَاعِثَهُ لاَ يَصِيرُ مُحْرِمًا وَلاَ يَحْرُمُ عَلَيْهِ شيء بِذَلِكَ
Sahih Muslim 1321 b

A hadith like this has been transmitted on the authority of Ibn Shihab.

وَحَدَّثَنِيهِ حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، بِهَذَا الإِسْنَادِ مِثْلَهُ ‏.‏
