Sayyiduna Abu Musa (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "When the Ash'aris are on a military expedition, or the food of their families in Madinah runs short, they gather it in a single cloth, then divide it among themselves equally by means of one vessel. They are of me, and I am of them."
