Volume 1, Book 4, Number 208:
Narrated Suwaid bin Al-Nu’man:
In the year of the conquest of Khaibar I went with Allah’s Apostle till we reached Sahba,’ a place
near Khaibar, where Allah’s Apostle offered the ‘Asr prayer and asked for food. Nothing but Sawrq
was brought. He ordered it to be moistened with water. He and all of us ate it and the Prophet got up
for the evening prayer (Maghrib prayer), rinsed his mouth with water and we did the same, and he
then prayed without repeating the ablution.
