question #3 Sahih al-Bukhari 500, Book 8, Hadith 147 : What items were used by the companions to assist the Prophet (ﷺ) during his visits to answer the call of nature?

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.
