Jabir told that God’s messenger prohibited invocations, and the family of ‘Amr b. Hazm came and said, “Messenger of God, we had an invocation proved efficacious which we applied for scorpion bite, but you have prohibited invocations.” They submitted it to him and he said, “I see no harm in it. If any of you is able to benefit his brother, let him do so.” Muslim transmitted it.
