What did the Prophet Muhammad (saw) do when water was brought for his ablution?
 Narrated `Aun bin Abi Juhaifa:                     that he had heard his father saying, "Allah's Apostle came to us at midday and water was brought for his ablution. He performed ablution and led us in Zuhr and `Asr prayers with a short stpear (or stick) planted in front of him (as a Sutra), while women and donkeys were passing beyond it."
