Abu al-Zubayr (may Allah have mercy on him) heard Sayyiduna Jabir (may Allah be pleased with him) say: A scorpion stung a man among us while we were sitting with the Prophet (peace and blessings be upon him). A man said: "O Messenger of Allah! Shall I perform ruqyah for him?" He (peace and blessings be upon him) said: "Whoever among you is able to benefit his brother, let him do so."
