From Sahih Muslim (Hadith 5727):
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
