Abdul-Rahman bin Abu Bakr reported,

We were with the Prophet ﷺ, one hundred and thirty in number, when the Prophet ﷺ asked, "Does any of you have food with him?"It turned out that one man had a saa of food or thereabouts, which was kneaded into dough. Then a tall, disheveled polytheist came along driving some sheep, and the Prophet ﷺ asked him, "Is this for sale, or a gift?"The man replied, "No, it is 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, there was not one of the one hundred and thirty without the Prophet ﷺ cutting off a piece of that roasted liver for him. If the man was present, he handed it to him directly, and if he was absent, he set his portion aside for him. Then he placed the meat in two large bowls, and we all ate and were filled, with food still 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 أعطاه إياه، وإن كان غائبا خبأها له، ثم جعل فيها قصعتين، فأكلنا أجمعون وشبعنا، وفضل في القصعتين، فحملته على البعير، أو كما قال.
