Sahih al-Bukhari Book 47, Hadith 3
We used to offer the `Asr prayer with the Prophet (ﷺ) and slaughter a camel, the meat of which would be
divided in ten parts. We would eat the cooked meat before sunset.
Once (on a journey) our provisions diminished and the people were reduced to poverty. They went to the Prophet (ﷺ) and asked his permission to slaughter their camels, and he agreed. `Umar met them and they told him about it, and he said, "How would you survive after slaughtering your camels?" Then he went to the Prophet and said, "O Allah's Messenger (ﷺ)! How would they survive after slaughtering their camels?" Allah's Messenger (ﷺ) ordered `Umar, "Call upon the people to bring what has remained of their food." A leather sheet was spread and all the food was collected and heaped over it. Allah's Messenger (ﷺ) stood up and invoked Allah to bless it, and then directed all the people to come with their utensils, and they started taking from it till all of them got what was sufficient for them. Allah's Messenger (ﷺ) then said, "I testify that None has the right to be worshipped but Allah, and I am His Messenger."
The Prophet (ﷺ) said, "When the people of Ash`ari tribe ran short of food during the holy battles, or the food of their families in Medina ran short, they would collect all their remaining food in one sheet and then distribute it among themselves equally by measuring it with a bowl. So, these people are from me, and I am from them."
