However, if the hole closes after its removal, and it becomes such that if she directs the water over it, it enters, and if she neglects it, it does not enter, she directs the water, and does not exert effort to introduce anything other than water; because what is considered is the predominant assumption of the water's arrival. See: Sharh al-Wiqayah p. 92, and al-Durr al-Mukhtar 1: 104.
