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 k

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

We used to garland the goats and send them (to Mecca), and Allah's Messenger (ﷺ) stayed back in Medina as a non-Muhrim ard nothing was forbidden for him (which is forbidden for a Muhrim).
وَحَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، حَدَّثَنَا عَبْدُ الصَّمَدِ، حَدَّثَنِي أَبِي، حَدَّثَنِي مُحَمَّدُ بْنُ جُحَادَةَ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ كُنَّا نُقَلِّدُ الشَّاءَ فَنُرْسِلُ بِهَا وَرَسُولُ اللَّهِ صلى الله عليه وسلم حَلاَلٌ لَمْ يَحْرُمْ عَلَيْهِ مِنْهُ شَىْءٌ ‏.‏
