Abdul-Rahman bin Abu Bakr reported,

The people of the Suffah were poor folk. The Prophet ﷺ once said, "Whoever has food for two, let him take a third with him. Whoever has food for four, let him take a fifth or sixth with him," or as he said.Abu Bakr brought three, and the Prophet ﷺ took ten with him. Abu Bakr along with three, meaning myself, my father, and my mother (and I do not know whether he also said my wife and our servant who moved between our house and Abu Bakr's house).Abu Bakr ate his evening meal at the Prophet's ﷺ home, then stayed until he had prayed the Isha prayer. Then he returned and stayed until the Messenger of Allah ﷺ had finished his meal. He came back after as much of the night had passed as Allah willed.His wife asked him, "What kept you from your guests?"He replied, "Have you not given them their evening meal?"She said, "They refused to eat until you came. They were offered food but declined."So I went and hid myself.Abu Bakr said, "You stupid fool!" He cursed and reviled, then said, "Eat!" And he said, "I will never eat it!"By Allah, we did not take a morsel except that more rose up from beneath it, until they were full, and the food became more than it had been before. Abu Bakr looked at it, and behold, it was as much as before or more.He said to his wife, "Sister of Banu Firas!"She replied, "No, by the coolness of my eyes, it is now three times more than it was before."So Abu Bakr ate from it and said, "That was only Satan," meaning his oath. Then he ate a morsel from it, then carried it to the Prophet ﷺ, where it remained until morning.There was a treaty between us and a people, and when the term expired, we divided into twelve men, with each man having a group of people with him, Allah knows how many were with each man. He sent some of the food with them, and they all ate from it, or as he said.

عن عبد الرحمن بن أبي بكر

أن أصحاب الصفة كانوا أناسا فقراء، وأن النبي ﷺ قال مرة: من كان عنده طعام اثنين فليذهب بثالث، ومن كان عنده طعام أربعة فليذهب بخامس أو سادس أو كما قال: وأن أبا بكر جاء بثلاثة، وانطلق النبي ﷺ بعشرة، وأبو بكر وثلاثة قال: فهو أنا وأبي وأمي ولا أدري هل قال: امرأتي وخادمي، بين بيتنا وبين بيت أبي بكر، وأن أبا بكر تعشى عند النبي ﷺ، ثم لبث حتى صلى العشاء، ثم رجع فلبث حتى تعشى رسول الله ﷺ، فجاء بعد ما مضى من الليل ما شاء الله، قالت له امرأته: ما حبسك عن أضيافك أو ضيفك؟ قال: أو عشيتهم؟ قالت: أبوا حتى تجيء، قد عرضوا عليهم فغلبوهم، فذهبت فاختبأت، فقال: يا غنثر فجدع وسب، وقال: كلوا، وقال: لا أطعمه أبدا، قال: وايم الله، ما كنا نأخذ من اللقمة إلا ربا من أسفلها أكثر منها حتى شبعوا، وصارت أكثر مما كانت قبل، فنظر أبو بكر: فإذا شيء أو أكثر، قال لامرأته: يا أخت بني فراس، قالت: لا وقرة عيني، لهي الآن أكثر مما قبل بثلاث مرات. فأكل منها أبو بكر وقال: إنما كان الشيطان، يعني يمينه، ثم أكل منها لقمة، ثم حملها إلى النبي ﷺ فأصبحت عنده، وكان بيننا وبين قوم عهد، فمضى الأجل فتفرقنا اثنا عشر رجلا، مع كل رجل منهم أناس، الله أعلم كم مع كل رجل، غير أنه بعث معهم، قال: أكلوا منها أجمعون. أو كما قال.
