Hadith 8:1806
Abu Bakr narrated to us, he said: Waki’ narrated to us, from Shu’bah, from ‘Aqil ibn Talhah, from Abu al-Husayb al-Qaysi, that he dedicated a camel on behalf of his mother, but he lost it. So he bought another one in its place and garlanded it. Then he found the first one, so he asked Ibn ‘Umar, who said: "Slaughter them both."
حدثنا أبو بكر قال حدثنا وكيع عن شعبة عن عقيل بن طلحة عن أبي الحصيب القيسي أنه أهدى عن أمه بدنة فأضلها فاشترى مكانه أخرى فقلدها ثم وجد الأولى فسأل بن عمر فقال انحرهما جميعا
