Hadith on Wudu: Performing ablution for every prayer

Anas ibn Malik reported: The Prophet, peace and blessings be upon him, would perform ablution at the time of every prayer. ‘Amr said, “How would you do so?” Anas said, “It is permissible for one of us to maintain ablution for multiple prayers, as long as he does not become ritually impure.”
