It is narrated from Abdullah bin Abi Bakr that he heard from Urwah bin Zubair that he went to Marwan bin Hakam and they discussed the things that necessitate ablution. Marwan said that touching the private part also necessitates ablution. Urwah said: I do not know this. Marwan said: Lady Busrah bint Safwan (may Allah be pleased with her) informed me, she heard from the Prophet (peace and blessings be upon him), he used to say: "When any one of you touches his private part, he should perform ablution."
