It was narrated that `Abdullah bin Sarjis said:"The Messenger of Allah forbade men to perform ablution with the water left over by a woman, and women to perform ablution with water left over by a man, however both (spouses) may start to perform their ablutions at the same time." Abu `Abdullah Ibn Majah said: "The first (narration) is correct, and the second (narration) is Wahm (an error)." Another chain with similar wording
