Answered by Shaykh Amjad Rasheed

Is it permissible to only use toilet paper when cleaning oneself after relieving oneself [h: or must one also use water]? Is it sufficient to wipe three times even if some feces remains unremoved by the toilet paper?

Yes, it is permissible for one to confine oneself to using toilet paper even if water is available. [h: However, this is only permissible] on the condition that there are at least three wipings when the substance of the filth is thereby removed. Otherwise, [h: if the substance is not removed after three wipings], it is obligatory to wipe more [h: than three times] until nothing remains except for a trace that could only be removed with water.
