It was narrated from ‘Aqqar bin Al-Mughirah from his father that the Prophet ﷺ said:
“Whoever seeks treatment by cauterization, or with Ruqyah, then he had absolved himself of reliance upon Allah.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنْ لَيْثٍ، عَنْ مُجَاهِدٍ، عَنْ عَقَّارِ بْنِ الْمُغِيرَةِ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ ﷺ قَالَ " مَنِ اكْتَوَى أَوِ اسْتَرْقَى فَقَدْ بَرِئَ مِنَ التَّوَكُّلِ " .
