We performed Hajj with the Messenger of Allah ﷺ, and we sacrificed a camel on behalf of seven people and a cow on behalf of seven people.
حدثنا وكيع حدثنا عزرة بن ثابت عن أبي الزبير
حججنا مع رسول الله ﷺ فنحرنا البعير عن سبعة والبقرة عن سبعة
Its isnad is sahih. Azra bin Thabit is trustworthy. The hadith occurred earlier at 14059.
