Sahih al-Bukhari 5737
Narrated Ibn `Abbas:
Some of the companions of the Prophet (ﷺ) passed by some people staying at a place where there was 
water, and one of those people had been stung by a scorpion. A man from those staying near the 
water, came and said to the companions of the Prophet, "Is there anyone among you who can do 
Ruqya as near the water there is a person who has been stung by a scorpion." So one of the Prophet's 
companions went to him and recited Surat-al-Fatiha for a sheep as his fees. The patient got cured and 
the man brought the sheep to his companions who disliked that and said, "You have taken wages for 
reciting Allah's Book." When they arrived at Medina, they said, ' O Allah's Messenger (ﷺ)! (This person) has 
taken wages for reciting Allah's Book" On that Allah's Messenger (ﷺ) said, "You are most entitled to take 
wages for doing a Ruqya with Allah's Book."
حَدَّثَنِي سِيدَانُ بْنُ مُضَارِبٍ أَبُو مُحَمَّدٍ الْبَاهِلِيُّ، حَدَّثَنَا أَبُو مَعْشَرٍ الْبَصْرِيُّ ـ هُوَ صَدُوقٌ ـ يُوسُفُ بْنُ يَزِيدَ الْبَرَّاءُ قَالَ حَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ الأَخْنَسِ أَبُو مَالِكٍ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ نَفَرًا، مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم مَرُّوا بِمَاءٍ فِيهِمْ لَدِيغٌ ـ أَوْ سَلِيمٌ ـ فَعَرَضَ لَهُمْ رَجُلٌ مِنْ أَهْلِ الْمَاءِ فَقَالَ هَلْ فِيكُمْ مِنْ رَاقٍ إِنَّ فِي الْمَاءِ رَجُلاً لَدِيغًا أَوْ سَلِيمًا‏.‏ فَانْطَلَقَ رَجُلٌ مِنْهُمْ فَقَرَأَ بِفَاتِحَةِ الْكِتَابِ عَلَى شَاءٍ، فَبَرَأَ، فَجَاءَ بِالشَّاءِ إِلَى أَصْحَابِهِ فَكَرِهُوا ذَلِكَ وَقَالُوا أَخَذْتَ عَلَى كِتَابِ اللَّهِ أَجْرًا‏.‏ حَتَّى قَدِمُوا الْمَدِينَةَ فَقَالُوا يَا رَسُولَ اللَّهِ أَخَذَ عَلَى كِتَابِ اللَّهِ أَجْرًا‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ إِنَّ أَحَقَّ مَا أَخَذْتُمْ عَلَيْهِ أَجْرًا كِتَابُ اللَّهِ ‏"‏‏.‏
