Zainab the wife of ‘Abdallah b. Mas'ud told that ‘Abdallah saw a thread on her neck and asked what it was. When she told him that it was a thread over which a spell had been recited for her he took it, cut it up and said, “You, family of ‘Abdallah, are independent of polytheism. I have heard God’s messenger say that spells, charms and love-spells are polytheism.”
She replied, “Why do you speak like this? My eye was discharging and I kept going to so and so, the Jew, and when he applied a spell to it it calmed down.”
‘Abdallah said, “That was just the work of the devil who was pricking it with his hand, and when a spell was uttered he desisted. All you need to do is to say as God’s messenger did, ‘Remove the harm, O Lord of men, and heal. Thou art the Healer. There is no remedy but Thine which leaves no disease behind.”
Kabsha daughter of Abu Bakra told that her father used to forbid his family to have themselves cupped on a Tuesday, and used to assert on the authority of God’s messenger that Tuesday is the day of blood in which there is an hour when it does not stop.
