Sahih al-Bukhari 5736

Muḥammad ibn Bashshār narrated to me: Ghundar narrated to us: Shuʿbah narrated to us, from Abū Bishr, from Abū al-Mutawakkil, from Abū Saʿīd al-Khudrī (may Allah be pleased with him): “Some of the Prophet’s ﷺ Companions came to a clan of the Arabs, but they did not provide them with hospitality. While they were in that state, the clan’s chief was stung. They said, ‘Do you have any medicine or anyone who can recite healing prayers?’ They replied, ‘You did not host us, so we will not do anything until you give us a reward.’ They agreed to give them a flock of sheep. One of them began reciting the Opening Chapter, gathering his saliva and spitting, and the man recovered. They brought them the sheep, but they said, ‘We will not take it until we ask the Prophet ﷺ.’ They asked him, and he laughed and said, ‘How did you know it was a healing recitation? Take it, and set aside a share for me.’”
