عن حكيمة بنت اميمة ابنت رقيقة عن امها انها قالت كان للنبى صلى الله عليه و سلم قدح من عيدان تحت سريره يبول فيه بالليل. (ابو داود 1/15)

Hukaima bint Umaymah reports from her mother saying: “Nabi (Sallallahu alaihi wasallam) had a wooden utensil kept under his bed (at the time he was ill) in which he would pass water during the night.”
