Hadith #1890 (Sunan Ibn Majah)
Book: The Chapters on Business Transactions
Narrator(s): Abu Bakr bin 'Ayyash al-Asadi أبو بكر بن عياش بن سالم الأسدي, al-Hasan bin 'Ali bin 'Affan الحسن بن علي بن عفان, Asim bin Abu al-Najud, Masrouq bin al-Ajda' مسروق بن الأجدع, Mu'adh ibn Jabal, Shaqayq bin Salmah al-Asadi شقيق بن سلمة الأسدي أبو وائل الكوفي, Yahya bin Aadm bin Sulaiman يحيى بن آدم بن سليمان

“The Messenger of Allah (ﷺ) sent us, thirty horsemen, on a military campaign. We camped near some people and asked them for hospitality but they refused. Then their leader was stung by a scorpion and they said: ‘Is there anyone among you who can recite Ruqyah for a scorpion sting?’ I said: ‘Yes, I can, but I will not recite Ruqyah for him until you give us some sheep.’ They said: ‘We will give you thirty sheep.’ So we accepted them, and I recited Al-Hamd (i.e. Al-Fatihah) over him seven times. Then he recovered, and I took the sheep. Then some doubts occurred within ourselves. Then we said: ‘Let us not hasten (to make a decision concerning the sheep) until we come to the Prophet (ﷺ)’ So when we came back: ‘I told him what I had done. He said: ‘How did you know that it is a Ruqyah? Divide them up and give me a share as well.'”
