Fatwa: Proof for cleansing an impurity thrice

It is in explicit texts. However, the questioner was supposed to ask if it is necessary for one to cleanse something soiled by an impurity three times or not and then ask us for the evidence. This is contrary to our view. In our view, it is not obligatory to purify an impure thing three times. Therefore how can one ask us the proof for something that is not our view? That which supports our view is in At-Tahreer. And it is that one cleanses something soiled by an impurity until it is removed only. And this is the chosen view.

As for the proof of cleansing three times, it is based on what is narrated by al-Hadi (as) with his chain of narrators from his father to his grandfather to Allah's Messenger, peace and blessings be upon him and his Progeny, with a connected chain of narrators that Allah's Messenger, peace and blessings be upon him and his Progeny, forbade a man who woke up from entering his hand into a container before washing his hands three times. This was narrated by al-Murtada Muhammad bin al-Hadi (as) who said: "My father, al-Hadi ila al-Haqq Yahya bin al-Hussein (as) related to me from his father from his grandfather with a connected chain..." with this wording. This hadith is well known and has been related by the two sheikhs [i.e. al-Bukhari and Muslim] in their Sahiihs as well as others with the same meaning.
