It is narrated from Sayf bin Ubaydullah al-Himyari: I and some other men with me came into the presence of Sayyidah Aishah (may Allah be pleased with her), and we asked her about a man who touches his private part and about a woman who touches her private part. She replied: I heard the Messenger of Allah (peace and blessings be upon him) say: "I do not care in the least whether I touch it (that is, my private part) or touch my nose."
The chain of this hadith is da'if (weak), because its narrators al-Mufaddal bin Thawab and Husayn bin Wadda' are majhul (unknown); however, in terms of its text this narration is evidence for those jurists who hold that touching the private part does not break ablution.
