باب اسْتِحْبَابِ الرُّقْيَةِ مِنَ الْعَيْنِ وَالنَّمْلَةِ وَالْحُمَةِ وَالنَّظْرَةِ ‏‏
Sahih Muslim 2199 e

Jabir reported Allah's Messenger (ﷺ) prohibited incantation. Then the people of Amr b. Hazm came to Allah's Messenger (ﷺ) and said:

We know an incantation which we use for curing the sting of the scorpion but you have prohibited it. They recited (the words of incantation) before him, whereupon he said: I do not see any harm (in it), so he who amongst you is competent to do good to his brother should do that.
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي سُفْيَانَ، عَنْ جَابِرٍ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الرُّقَى فَجَاءَ آلُ عَمْرِو بْنِ حَزْمٍ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالُوا يَا رَسُولَ اللَّهِ إِنَّهُ كَانَتْ عِنْدَنَا رُقْيَةٌ نَرْقِي بِهَا مِنَ الْعَقْرَبِ وَإِنَّكَ نَهَيْتَ عَنِ الرُّقَى ‏.‏ قَالَ فَعَرَضُوهَا عَلَيْهِ ‏.‏ فَقَالَ ‏ "‏ مَا أَرَى بَأْسًا مَنِ اسْتَطَاعَ مِنْكُمْ أَنْ يَنْفَعَ أَخَاهُ فَلْيَنْفَعْهُ ‏"‏ ‏.‏
