Salama bin Akwa reported,

We set out with the Messenger of Allah ﷺ on a military expedition, and we became so hard-pressed that we considered slaughtering some of our riding animals. The Prophet of Allah ﷺ then ordered us to gather our provision-bags, so we spread out a leather mat for him, and the people's provisions were piled up on it.He said, "I stretched up to estimate how much there was, and I judged it to be about the size of a crouching goat. We were fourteen hundred men. We ate until we were all full, then we filled our provision-bags."Then the Prophet of Allah ﷺ asked, "Is there any water for ablution?"A man came with a small water-skin containing a little water and emptied it into a bowl. All fourteen hundred of us performed ablution from it, pouring it generously.After that, eight more men came and asked, "Is there any water for purification?"The Messenger of Allah ﷺ replied, "The water for ablution is finished."

عن سلمة بن الأكوع قال

خرجنا مع رسول الله ﷺ في غزوة فأصابنا جهد. حتى هممنا أن ننحر بعض ظهرنا. فأمر نبي الله ﷺ فجمعنا مزاودنا. فبسطنا له نطعا. فاجتمع زاد القوم على النطع. قال: فتطاولت لأحرزه كم هو؟ فحزرته كربضة العنز. ونحن أربع عشرة مائة. قال: فأكلنا حتى شبعنا جميعا. ثم حشونا جربنا. فقال نبي الله ﷺ: فهل من وضوء؟ قال: فجاء رجل بإداوة له، فيها نطفة. فأفرغها قدح فتوضأنا كلنا. ندغفقه دغفقة. أربع عشرة مائة. قال: ثم جاء بعد ذلك ثمانية فقالوا: هل من طهور؟ فقال رسول الله ﷺ: فرغ الوضوء.
