Hazrat Urwah bin Zubair narrates that my father related to me that Marwan discussed with me the issue of touching the private part. I said that there is no (need for) ablution in this matter. He said that Busrah bint Safwan has narrated a hadith about this. Then he sent a messenger to Busrah, who came back and reported that she states that the Messenger of Allah (peace and blessings be upon him) said: Whoever touches his private part with his hand should perform ablution.

Hazrat Ibn Sirin says that I asked Hazrat Ubaidah about the saying of Allah Almighty { أَوْ لاَمَسْتُمُ النِّسَائَ }, so he gestured with his hand, and I understood what he wanted to say, so I did not ask him further. He said that I have been informed that Hazrat Ibn Umar (may Allah be pleased with them both) used to perform ablution when he touched the private part. Muhammad says that I think the statement of Hazrat Ibn Umar (may Allah be pleased with them both) and Hazrat Ubaidah is the same.
