(Fourth chain) Urwah bin Zubair narrates, while he was with his father, that Marwan related this hadith to him through the mediation of Lady Busrah bint Safwan (may Allah be pleased with her), that the Messenger of Allah, peace and blessings be upon him, said: Whoever touches his private part should perform ablution. Then Marwan sent a messenger to her, while I was present, and the Lady (may Allah be pleased with her) replied: Yes, (the Messenger of Allah, peace and blessings be upon him, said exactly that), so the messenger returned with the same statement from her.
