Sayf bin Abdullah al-Himyari says: I, along with some other men, went to Sayyidah Aishah (may Allah be pleased with her), and we asked her about a man who touches his private part. She said: I heard the Prophet (peace and blessings be upon him) say: "I do not care whether I have touched it (that is, the private part) or my nose."
Abu Ya'la recorded it from a man of the people of al-Yamamah, from Husayn bin Daffa', from his father, from Sayf; all of them are majhul (unknown), and that is the least that can be said about them.
