On the day of Hudaybiyah we numbered fourteen hundred. Hudaybiyah was a well, and we drew from it until we did not leave a single drop. The Prophet ﷺ sat on the edge of the well, called for water, rinsed his mouth, and spat it back into the well. We waited only a short while, then drew water until we had drunk our fill and our mounts had drunk their fill, or until our mounts moved on.
كنا يوم الحديبية أربع عشرة مائة والحديبية بئر، فنزحناها حتى لم نترك فيها قطرة، فجلس النبي ﷺ على شفير البئر فدعا بماء فمضمض ومج في البئر، فمكثنا غير بعيد، ثم استقينا حتى روينا وروت أو صدرت ركائبنا.
Bukhari related it in the Signs of Prophethood (3577) from Malik bin Ismail, who said, "Israil related to us, from Abu Ishaq, from Bara," and he mentioned it.
