Narrated Abu Bashir Al-Ansari:
That he was in the company of Allah's Messenger (ﷺ) on some of his journeys. (The sub-narrator `Abdullah adds, "I think that Abu Bashir also said, 'And the people were at their sleeping places.") Allah's Apostle sent a messenger ordering: "There shall not remain any necklace of string or any other kind of necklace round the necks of camels except it is cut off."
Narrated Um Salama:
that the Prophet (ﷺ) saw in her house a girl whose face had a black spot. He said. "She is under the effect of an evil eye; so treat her with a Ruqya."
Abu Bashir Ansari reported that he had had (the opportunity of accompanying Allah's Messenger (ﷺ) in some of his journeys. Allah's Messenger (ﷺ) sent one of his messengers 'Abdullah b Abi Bakr said: I think he said (these words) when the people were at the places of rest: No necklace of strings be left on the necks of the camels or the necklace kept unbroken. Imam Malik said: To my mind (this practice) of wearing necklace round the necks of camels or animals was because of the fact that they (wanted to save them) from the influence of the evil eye.
Umm Salama, the wife of Allah's Messenger (ﷺ), reported that Allah's Messenger (ﷺ) said to a small girl in the house of Umm Salama that he had been seeing on her face black stains and told her that that was due to the influence of an evil eye, and he asked that she should be cured with the help of invocation (hoping) that her face should become spotless.
