عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا أَنْزَلَ اللَّهُ دَاء إِلا أنزل لَهُ دَوَاء» . رَوَاهُ البُخَارِيّ

‘Auf b. Malik al-Ashja‘i said

In the pre-Islamic period we used to apply spells, and we asked God’s messenger how he looked upon that. He replied, “Submit your spells to me. There is no harm in spells so long as they involve no polytheism.” Muslim transmitted it.
