Al-Husayn ibn Sa’id from Fadalah from Rifa‘ah ibn Musa who said: I asked Abu Abdillah عليه السلام, peace be upon him, about performing ablution in the mosque. Imam عليه السلام disliked it when it was after defecation or urination. (meaning dislike ‘karahah’ for doing wudu in the mosque when the cause for purification was relieving oneself)
