كتاب الحج

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 a

'A'isha (Allah be pleased with her) reported that Allah's Messenger (ﷺ) sent the sacrificial animals from Medina. I wove garlands for his sacrificial animals (and then he hung them round their necks), and he would not avoid doing anything which the Muhrim avoids.

وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَمُحَمَّدُ بْنُ رُمْحٍ، قَالاَ أَخْبَرَنَا اللَّيْثُ، ح وَحَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا لَيْثٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، وَعَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، أَنَّ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُهْدِي مِنَ الْمَدِينَةِ فَأَفْتِلُ قَلاَئِدَ هَدْيِهِ ثُمَّ لاَ يَجْتَنِبُ شَيْئًا مِمَّا يَجْتَنِبُ الْمُحْرِمُ ‏.‏
