It was narrated that 'Abdullah bin Salamah said: "I entered upon 'Ali bin Abu Talib and he said: 'The Messenger of Allah (ﷺ) used to go to the lavatory and relieve himself, then come out, and he would eat bread and meat with us and recite Qur'an, nothing stopped him' or perhaps he said: 'prevented him from doing so except sexual impurity.'"
