Muwatta Malik, Book 20, Hadith 758 (In-Book) ⓘ

Yahya related to me from Malik that Yahya ibn Said said, "I asked Amra bint Abd ar-Rahman if there was anything that was haram for someone who sent a sacrificial animal (to Makka) but did not go there himself, and she told me that she had heard A'isha say, 'It is only some one who goes into ihram for hajj and begins saying the talbiya for whom things are haram.' "

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّهُ قَالَ سَأَلْتُ عَمْرَةَ بِنْتَ عَبْدِ الرَّحْمَنِ عَنِ الَّذِي، يَبْعَثُ بِهَدْيِهِ وَيُقِيمُ هَلْ يَحْرُمُ عَلَيْهِ شَىْءٌ فَأَخْبَرَتْنِي أَنَّهَا سَمِعَتْ عَائِشَةَ تَقُولُ لاَ يَحْرُمُ إِلاَّ مَنْ أَهَلَّ وَلَبَّى ‏.‏
