Sayyidina Abu Saeed (RA) narrated Allah’s Messenger sent us on an expedition. We halted at a place and requested its people for their hospitality, but they declined to host us. Meanwhile, a scorpion stung their chief, so they came to us and asked if we had anyone who would cure him through ruqyah. I said, “Yes, I will. But, I will not blow on him until you give us sheep.” They said, “We will give you thirty sheep.” We agreed, I recited al-Fatihah over him seven times and he was relieved (of poison), and we took the sheep. Then we had doubt about it and we said, “Do not make haste till we come to Allah’s Messenger (SAW). When we came to him, I mentioned to him what I had done. He asked, “How did you know that it (al-Fatihah) is a ruqyah. Take the sheep and count me with you for my share.”
