Musannaf Ibn Abi Shaybah 25099 — Ruqyah for scorpion stings: what

It is narrated from Muhammad bin Ali. He said: One night the Prophet (peace and blessings be upon him) was praying when he placed his blessed hand on the ground, and a scorpion stung him. He caught that scorpion with his sandal and killed it. Then, when he had finished the prayer, he said: "May Allah curse the scorpion! It spares neither one who prays nor one who does not." Or he said: "Neither a prophet nor anyone else." Then he called for salt and water and placed it in a vessel. Then he began pouring this water on his finger at the place where the scorpion had stung him, wiping it, and reciting the Mu'awwidhatayn over it for protection.
