Bara bin Azib reported,

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 in it. The Prophet ﷺ sat on the edge of the well and called for water. He rinsed his mouth and spat it into the well. We waited only a short while, then drew from it until we had drunk our fill and our mounts had drunk their fill, or our mounts went on their way.

حدثنا مالك بن إسماعيل حدثنا إسرائيل عن أبي إسحاق

عن البراء رضي الله عنه قال

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
