"A'isha reported that a Jew from among the Jews of Banu Zuraiq who was called Labid b. al-A'sam cast spell upon Allah's Messenger (may peace be upon him) with the result that he (under the influence of the spell) felt that he had been doing something whereas in fact he had not been doing that. (This state of affairs lasted) until one day or during one night Allah's Messenger (may peace be upon him) made supplication (to dispel its effects). He again made a supplication and he again did this and said to 'A'isha: Do you know that Allah has told me what I had asked Him? There came to me two men and one amongst them sat near my head and the other one near my feet and he who sat near my head said to one who sat near my feet or one who sat near my feet said to one who sat near my head: What is the trouble with the man? He said: The spell has affected him. He said: Who has cast that? He (the other one) said: It was Labid b. A'sam (who has done it). He said: What is the thing by which he transmitted its effect? He said: By the comb and by the hair stuck to the comb and the spathe of the date-palm. He said: Where is tbap He replied: In the well of Dhi Arwan. She said: Allah's Messenger (may peace be upon him) sent some of the persons from among his Companions there and then said: 'A'isha. by Allah, its water was yellow like henna and its trees were like heads of the devils. She said that she asked Allah's Messenger (may peace be upon him) as to why he did not burn that. He said: No, Allah has cured me and I do not like that I should induce people to commit any high-handedness in regard (to one another), but I only commanded that it should be buried."
