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."

Narrated Anas Ibn Malik: Whenever the Prophet went for answering the call of nature, I and another boy used to go after him with a staff, a stick or a short spear (or stick) and a tumbler of water and when he finished from answering the call of nature we would hand that tumbler of water to him.
