The Messenger of Allah ﷺ and his companions were brought some parched barley meal, and they chewed it. Muaz followed the same wording in his narration from Shuba.
حدثني محمد بن بشار حدثنا ابن أبي عدي عن شعبة عن يحيى بن سعيد عن بشير بن يسار
كان رسول الله ﷺ وأصحابه أتوا بسويق فلاكوه تابعه معاذ عن شعبة
