It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that the Messenger of Allah (peace and blessings be upon him) said: "Pain in the flank (khasirah) is the pain of the vein of the kidney; when it stirs, it hurts the one who has it, so treat it with burnt water and honey."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Imam al-Zuhri (may Allah have mercy on him) except Abd al-Rahman bin Muhammad al-Madini; Muslim bin Khalid al-Zanji is alone in narrating it."
