His statement عليه السلام, "Do not perform wudu from such water except in case of necessity," indicates the dislike of immersing oneself in it. For if it were not disliked, the permission for wudu and ghusl from it would not have been restricted to cases of necessity. However, the evidence that immersion does not invalidate the water if it exceeds the volume of a kurr is found in the earlier narrations, which state that if the water reaches the volume of a kurr, nothing can render it impure.
