حدثنا علي بن عبد الله، حدثنا سفيان، قال يحيى بن سعيد سمعت بشير بن يسار، يقول حدثنا سويد بن النعمان، قال خرجنا مع رسول الله صلى الله عليه وسلم إلى خيبر، فلما كنا بالصهباء  قال يحيى وهى من خيبر على روحة  دعا رسول الله صلى الله عليه وسلم بطعام، فما أتي إلا بسويق، فلكناه فأكلنا منه، ثم دعا بماء فمضمض ومضمضنا، فصلى بنا المغرب ولم يتوضأ‏.‏ قال سفيان سمعته منه عودا وبدءا‏.‏
 Narrated Suwaid bin An-Nu`man:                     We went out with Allah's Apostle to Khaibar, and when we were at As-Sahba', (Yahya, a sub-narrator said, "As-Sahba' is a place at a distance of one day's journey to Khaibar)." Allah's Apostle asked the people to bring their food, but there was nothing with the people except Sawiq. So we all chewed and ate of it. Then the Prophet asked for some water and he rinsed his mouth, and we too, rinsed our mouths. Then he led us in the Maghrib prayer without performing ablution (again).
