He (the Holy Prophet) commanded us as we had entered into the state of Ihram to sacrifice the animals (as a rite of Hajj) and a group (of person; amongst us, i. e. seven) shared in the sacrifice of one (camel or cow), and it happened at that time when he commanded them to put off Ihram for Hajj (after performing 'Umra). (Using translation from Muslim 1318e)
عَنْ حَجَّةِ النَّبِيِّ ﷺ قَالَ فَأَمَرَنَا النَّبِيُّ ﷺ إِذَا أَحْلَلْنَا أَنْ نُهْدِيَ وَيَجْتَمِعُ النَّفَرُ مِنَّا فِي الْهَدِيَّةِ وَذَلِكَ حِينَ أَمَرَهُمْ أَنْ يَحِلُّوا مِنْ حَجَّتِهِمْ
