Zaynab, the wife of Abdullah ibn Mas'ud, told that Abdullah said: I heard the Messenger of Allah ﷺ saying: spells, charms and love-potions are polytheism. I asked: Why do you say this? I swear by Allah, when my eye was discharging I used to go to so-and-so, the Jew, who applied a spell to me. When he applied the spell to me, it calmed down. Abdullah said: That was just the work of the Devil who was picking it with his hand, and when he uttered the spell on it, he desisted. All you need to do is to say as the Messenger of Allah ﷺ used to say: Remove the harm, O Lord of men, and heal. Thou art the Healer. There is no remedy but Thine which leaves no disease behind.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ الرُّقَى وَالتَّمَائِمَ وَالتِّوَلَةَ شِرْكٌ قَالَتْ قُلْتُ لِمَ تَقُولُ هَذَا وَاللَّهِ لَقَدْ كَانَتْ عَيْنِي تَقْذِفُ وَكُنْتُ أَخْتَلِفُ إِلَى فُلاَنٍ الْيَهُودِيِّ يَرْقِينِي فَإِذَا رَقَانِي سَكَنَتْ فَقَالَ عَبْدُ اللَّهِ إِنَّمَا ذَاكِ عَمَلُ الشَّيْطَانِ كَانَ يَنْخَسُهَا بِيَدِهِ فَإِذَا رَقَاهَا كَفَّ عَنْهَا إِنَّمَا كَانَ يَكْفِيكِ أَنْ تَقُولِي كَمَا كَانَ رَسُولُ اللَّهِ ﷺ يَقُولُ أَذْهِبِ الْبَاسَ رَبَّ النَّاسِ اشْفِ أَنْتَ الشَّافِي لاَ شِفَاءَ إِلاَّ شِفَاؤُكَ شِفَاءً لاَ يُغَادِرُ سَقَمًا  

The Prophet ﷺ said: No spell is to be used except for the evil eye or a scorpion sting.  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ رُقْيَةَ إِلاَّ مِنْ عَيْنٍ أَوْ حُمَةٍ
