The Prophet ﷺ set out on one of his journeys with a group of his companions. As they traveled along, the time for prayer arrived, but they could not find any water for ablution. One of the men went off and returned with a small cup containing a little water. The Prophet ﷺ took it and performed ablution, then he stretched his four fingers over the cup and said, "Come, perform your ablution."So the people performed ablution, and each of them was able to complete his ablution as he wished. They numbered around seventy men.
حدثنا عبد الرحمن بن مبارك حدثنا حزم قال سمعت الحسن قال حدثنا
خرج النبي ﷺ في بعض مخارجه ومعه ناس من أصحابه فانطلقوا يسيرون فحضرت الصلاة فلم يجدوا ماء يتوضئون فانطلق رجل من القوم فجاء بقدح من ماء يسير فأخذه النبي ﷺ فتوضأ ثم مد أصابعه الأربع على القدح ثم قال قوموا فتوضئوا فتوضأ القوم حتى بلغوا فيما يريدون من الوضوء وكانوا سبعين أو نحوه
