Sahih Muslim 2199a
Jabir b. 'Abdullah reported that Allah's Apostle ﷺ granted a special sanction for incantation in case of the snake poison to a tribe of 'Amr. Abu Zubair said: I heard Jabir b. 'Abdullah as saying that the scorpion stung one of us as we were sitting with Allah's Messenger (may peace upon him). A person said: Allah's Messenger, I use incantation (for curing the effect. of sting), whereupon he said: He who is competent amongst you to benefit his brother should do so.
وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ، حَدَّثَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي أَبُو الزُّبَيْرِ أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ أَرْخَصَ النَّبِيُّ ﷺ فِي رُقْيَةِ الْحَيَّةِ لِبَنِي عَمْرٍو . قَالَ أَبُو الزُّبَيْرِ وَسَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ لَدَغَتْ رَجُلاً مِنَّا عَقْرَبٌ وَنَحْنُ جُلُوسٌ مَعَ رَسُولِ اللَّهِ ﷺ . فَقَالَ رَجُلٌ يَا رَسُولَ اللَّهِ أَرْقِي قَالَ " مَنِ اسْتَطَاعَ مِنْكُمْ أَنْ يَنْفَعَ أَخَاهُ فَلْيَفْعَلْ " .
