We were with the Messenger of Allah ﷺ on a journey when the Day of Sacrifice arrived, so we shared a camel among ten people and a cow among seven.
أخبرنا محمد بن عبد العزيز بن غزوان قال حدثنا الفضل بن موسى عن حسين يعني ابن واقد عن علباء بن أحمر عن عكرمة
كنا مع رسول الله ﷺ في سفر فحضر النحر فاشتركنا في البعير عن عشرة والبقرة عن سبعة
