Mukhtasar Sahih Bukhari — Hadith 1132

Abu Musa (may Allah be pleased with him) reports that the Prophet Muhammad (peace and blessings be upon him) said: "When the people of the Ash'ari tribe run short of provisions during a campaign, or when the food of their families in Madinah becomes scarce, they gather all their possessions in one cloth and then distribute it among themselves equally with a single measure. So, they are from me and I am from them."
