Jabir ibn Abdullah reported: A man was stung by a scorpion while we were sitting with the Messenger of Allah, peace and blessings be upon him. Another man said, “O Messenger of Allah, I will supplicate over him.” The Prophet said, “Whoever among you is able to benefit his brother, then let him do so.”
