Narrated `Aun bin Abi Juhaifa
that he had heard his father saying, "Allah's Messenger (ﷺ) 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 (ﷺ) 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.
