It is narrated from Sayyidah Salma (may Allah be pleased with her), the maidservant of the Messenger of Allah (peace and blessings be upon him), that whenever anyone complained to the Messenger of Allah (peace and blessings be upon him) of a pain in his head, he (peace and blessings be upon him) would tell him: "Have cupping done (hijamah)," and whenever anyone complained of pain in his feet, he (peace and blessings be upon him) would say: "Apply henna to them." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
