I was emailed the other incident I was looking for incase anyone was wondering:
Here you go:
It was narrated from Zaynab the wife of ‘Abdullaah Ibn Mas’ud (radiallaahu anhu) from ‘Abdullaah (radiallaahu anhu) that he said:
“I heard the Messenger of Allaah (peace and blessings of Allaah be upon him) say, ‘Spells (ruqyah), amulets and love-charms are shirk.” I said, “Why do you say this? By Allaah, my eye was weeping with a discharge and I kept going to So and so, the Jew, who did a spell for me. When he did the spell, it calmed down.” ‘Abdullaah said: “That was just the work of the Shaytaan who was picking it with his hand, and when (the Jew) uttered the spell, he stopped. All you needed to do was to say as the Messenger of Allaah (peace and blessings of Allaah be upon him) used to say: ‘Adhhib il-ba’s Rabb al-naas ishfi anta al-Shaafi laa shifaa’a illa shifaa’uka shifaa’an laa yughaadiru saqaman (Remove the harm, O Lord of mankind, and heal, You are the Healer. There is no healing but Your healing, a healing which leaves no disease behind.’”
(Narrated by Abu Dawud:3883, Ibn Maajah:3530)
