It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that in the time of the Messenger of Allah (peace and blessings be upon him) water was scarce, and when it was summer the people would pray Zuhr and then go out (to rest and cool off). Once the Messenger of Allah (peace and blessings be upon him) led the Zuhr prayer, then he (peace and blessings be upon him) went out, and the people also went out with him (peace and blessings be upon him) to the courtyard of the mosque. He (peace and blessings be upon him) stayed there until, when the time of the call to prayer drew near, he (peace and blessings be upon him) sent me to the house of the Mother of the Believers, Sayyidah Umm Salamah (may Allah be pleased with her), to bring him (peace and blessings be upon him) water for ablution. I went and came back with a bowl that was two-thirds or half full of water. He (peace and blessings be upon him) performed ablution, and when he (peace and blessings be upon him) had finished his ablution, some of the water of his (peace and blessings be upon him) ablution was left over in the bowl. He (peace and blessings be upon him) raised his blessed head and saw the people standing (waiting), and he (peace and blessings be upon him) asked: "Who are these people?" Sayyiduna Anas (may Allah be pleased with him) said: I said: O Messenger of Allah, they have no water available for ablution. He (peace and blessings be upon him) said: "Call them." I called them, and the people came, and the Messenger of Allah (peace and blessings be upon him) put his blessed hand into the water left over in the bowl. By the One in whose Hand is my soul, not a single person among them remained who did not perform ablution with the water (flowing) from the blessed palm of the Messenger of Allah (peace and blessings be upon him), and even after that some water was left in the bowl, which I took back to the house.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Sharik bin Abi Namir (may Allah have mercy on him) except Sa'id bin Salamah (may Allah have mercy on him)."
