Is it sufficient to use a stone for ritual cleansing after impurity if the stone was previously used for cleansing and subsequently washed or had the soiled part broken off?

Primary text

It is sufficient for the person to use the stone if the process of cleansing was repeated three times, because the stone is generally permissible for use in ritual cleansing by others. A dissenting view, attributed to Abu Bakr, suggests it is not sufficient, based on strictly adhering to the literal wording of the permission.
