It is narrated from Sayyiduna Suwaid bin Nu’man (may Allah be pleased with him), he says: In the year of Khaybar, we set out with the Messenger of Allah (peace and blessings be upon him). When we reached the place of Sahba, the Prophet (peace and blessings be upon him) performed the ‘Asr prayer and asked for food. Only sattu (roasted barley flour) was brought. The people ate and drank, then the Prophet (peace and blessings be upon him) rinsed his mouth and stood up for the Maghrib prayer, and we also rinsed our mouths, and the Prophet (peace and blessings be upon him) did not even touch water (for ablution).
