Musannaf Ibn Abi Shaybah 1206 — Those who disliked urinating

Abd Rabbih bin Abi Rashid said: I asked Raytah (the slave-woman of Anas) whether Sayyiduna Anas (may Allah be pleased with him) used to urinate in his bathing room. She said: No; rather, I used to place a copper vessel for him, and he would urinate in it.
