Mukhtasar Bukhari (Abridged) 144 — Using leftover water from others’

Narrated Sayyiduna Abu Juhaifah (may Allah be pleased with him): (One day) the Prophet Muhammad (peace and blessings be upon him) came to us at midday, and water for ablution was brought to him. So, he performed ablution. When he had finished ablution, the people began to take the leftover water from his ablution and started rubbing it on their faces and eyes. Then the Prophet Muhammad (peace and blessings be upon him) offered two rak‘ahs of Zuhr and two rak‘ahs of ‘Asr (shortened), and in front of him a spear (i.e., a lance) was fixed as a sutrah (barrier).
