وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا أَبُو خَيْثَمَةَ، عَنْ عَاصِمٍ الأَحْوَلِ، عَنْ يُوسُفَ بْنِ، عَبْدِ اللَّهِ عَنْ أَنَسِ بْنِ مَالِكٍ، فِي الرُّقَى قَالَ رُخِّصَ فِي الْحُمَةِ وَالنَّمْلَةِ وَالْعَيْنِ .Anas b. Malik reported in connection with incantation that he had been granted sanction (to use incantation as a remedy) for the sting of the scorpion and for curing small pustules and dispelling the influence of an evil eye
From Sahih Muslim, whose reports the scholars accept as authentic.
