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 j

'A'isha (Allah be pleased with her) reported:

Allah's Messenger (may peace be upon, him) sent some goats as sacrificial animals to the House and He garlanded them.
وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَأَبُو كُرَيْبٍ قَالَ يَحْيَى أَخْبَرَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ أَهْدَى رَسُولُ اللَّهِ صلى الله عليه وسلم مَرَّةً إِلَى الْبَيْتِ غَنَمًا فَقَلَّدَهَا ‏.‏
