Abdul-Rahman bin Abu Bakr reported,

We were with the Prophet ﷺ, a hundred and thirty in number. The Prophet ﷺ asked, "Does any of you have food with him?"It turned out that one man had about a saa of food or so, which was kneaded into dough. Then a tall, disheveled idolater came along, driving sheep before him.The Prophet ﷺ asked, "Is this for sale, or a gift?"The man replied, "No, for sale."So he bought a sheep from him, and it was prepared. The Prophet of Allah ﷺ ordered that the liver and what surrounds it be roasted. By Allah, every one of the hundred and thirty had a portion cut for him from that roasted liver. Whoever was present was given his share, and whoever was absent had his share set aside for him. Then he placed the meat in two large bowls, and we all ate and were satisfied, and there was still food left over in the two bowls, which I loaded onto the camel, or as he said.

عن عبد الرحمن بن أبي بكر قال

كنا مع النبي ﷺ ثلاثين ومائة، فقال النبي ﷺ: هل مع أحد منكم طعام فإذا مع رجل صاع من طعام أو نحوه، فعجن، ثم جاء رجل مشرك مشعان طويل، بغنم يسوقها، فقال النبي ﷺ: أبيع أم عطية أو قال: هبة قال: لا، بل بيع، قال: فاشترى منه شاة فصنعت، فأمر نبي الله ﷺ بسواد البطن يشوى، وايم الله، ما من الثلاثين ومائة إلا قد حز له حزة من سواد بطنها، إن كان شاهدا أعطاها إياه، وإن كان غائبا خبأها له، ثم جعل فيها قصعتين، فأكلنا أجمعون وشبعنا، وفضل في القصعتين، فحملته على البعير، أو كما قال.
