باب جَوَازِ أَخْذِ الأُجْرَةِ عَلَى الرُّقْيَةِ بِالْقُرْآنِ وَالأَذْكَارِ ‏‏
Sahih Muslim 2201 d

This hadith has been narrated on the authority of Hisham with the same chain of transmitters and he said:

There stood up with her a person amongst us whom we did not know before as an incantator.
وَحَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ، حَدَّثَنَا هِشَامٌ، بِهَذَا الإِسْنَادِ ‏.‏ نَحْوَهُ غَيْرَ أَنَّهُ قَالَ فَقَامَ مَعَهَا رَجُلٌ مِنَّا مَا كُنَّا نَأْبِنُهُ بِرُقْيَةٍ ‏.‏
