The Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), narrates that the Prophet (peace and blessings be upon him) said: "Clean yourselves after relieving yourselves (istinja) with cold water, for it brings health against piles."
No one narrated this hadith from Hisham bin Urwah (may Allah have mercy on him) except Abu al-Rabi' al-Samman (may Allah have mercy on him), and Ammar (may Allah have mercy on him) is alone in narrating it from him.
