Silsilat al-Ahadith al-Sahihah

Abu Bakr bin Sulaiman bin Abu Hathmah Qurashi says that an Ansari man developed a boil on his side. He was informed that Sayyida Shifa bint Abdullah (may Allah be pleased with her) performs ruqyah (incantation) on such boils. He went to her and requested her to perform ruqyah on him. She said: "By Allah! Since I accepted Islam, I have not performed ruqyah on anyone." The Ansari went to the Messenger of Allah (peace and blessings be upon him) and informed him of everything Shifa had said. The Prophet (peace and blessings be upon him) called Shifa and said to her, "Present your ruqyah to me." She did so, and the Prophet (peace and blessings be upon him) said: "Perform ruqyah on the Ansari and teach Hafsa this ruqyah, just as you previously taught her writing."
