It wasnarrated that Zainab said:
"There was an old woman who used toenter upon us and perform Ruqyah from erysipelas: Contagious diseasewhich causes fever and leaves a red coloration of the skin. We had abed with long legs, and when 'Abdullah entered he would clear histhroat and make noise. He entered one day and when she heard hisvoice she veiled herself from him. He came and sat beside me, andtouched me, and he found a sting. He said: 'What is this?' Isaid: 'An amulet against erysipelas.' He pulled it, broke it andthrew it away, and said: 'The family of 'Abdullah has no need ofpolytheism.' I heard the Messenger of Allah (ﷺ) say: "Ruqyah(i.e., which consist of the names of idols and devils etc.), amuletsand Tiwalah (charms) are polytheism.'""I said: 'I went out one day and so-and-so looked at me, and my eye began to water on the side nearest him. When I recited Ruqyah for it, it stopped, but if I did not recite Ruqyah it watered again.' He said: 'That is Satan, if you obey him he leaves you alone but if you disobey him he pokes you with his finger in your eye. But if you do what the Messenger of Allah (ﷺ) used to do, that will be better for you and more effective in healing. Sprinkle water in your eye and say: Adhhibil-bas Rabban-nas, washfi Antash-Shafi, la shifa'a illa shafi'uka, shafi'an la yughadiru saqaman (Take away the pain, O Lord of mankind, and grant healing, for You are the Healer, and there is no healing but Your healing that leaves no trace of sickness).'"
