Abu al-Muthanna said: I was with Marwan when Sayyiduna Abu Sa'id (may Allah be pleased with him) came and narrated that a man said: O Messenger of Allah! I do not become satisfied in one breath? The Prophet (peace be upon him) said: "Then remove the cup from your mouth and then take a breath." He asked: What if I see something dirty in it? He said: "Pour it out."

Sayyiduna Abu Qatadah (may Allah be pleased with him) narrated that he heard the Prophet Muhammad (peace and blessings be upon him) say: "When any one of you urinates, he should not hold his private part with his right hand, nor should he clean himself with his right hand, and he should not breathe into the vessel."
