Sayyiduna Abu Juhayfah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) came out in the midday heat. Ablution water was brought to him (peace and blessings be upon him) and he (peace and blessings be upon him) performed ablution, and the people began taking from the leftover water of his (peace and blessings be upon him) ablution and rubbing it over their bodies. Then he (peace and blessings be upon him) led Zuhr in two rak'ahs and Asr in two rak'ahs, while there was a spear in front of him (peace and blessings be upon him).
These are the words of the narration of Asim bin Ali, and the other narrators reported something similar.
