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
وَحَدَّثَنَا سَعِيدُ بْنُ مَنْصُورٍ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ عَائِشَةَ، تَقُولُ كُنْتُ أَفْتِلُ قَلاَئِدَ هَدْىِ رَسُولِ اللَّهِ صلى الله عليه وسلم بِيَدَىَّ هَاتَيْنِ ثُمَّ لاَ يَعْتَزِلُ شَيْئًا وَلاَ يَتْرُكُهُ.
Abd al-Rahman b. al-Qasim reported on the authority of his father that he heard 'A'isha (Allah be pleased with her) saying: I used to weave garlands for the sacrificial animals of Allah's Messenger (ﷺ) with these hands of mine, but he (Allah's Messenger) neither avoided anything nor gave up anything (which a Muhrim should avoid or give up).
