Whoever is able to benefit his brother, let him do so

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that a man of the Ansar called Amr bin Hazm came; he used to recite ruqyah for snakebite. He said: O Messenger of Allah, you have forbidden ruqyah, while I recite ruqyah for snakebite. He (peace and blessings be upon him) said: "Recite it to me." He recited it, and he (peace and blessings be upon him) said: "There is no harm in this; these are covenants (mawathiq)." The narrator said: And my maternal uncle from the Ansar also came; he used to recite ruqyah for scorpion stings. He too said that you have forbidden ruqyah, and he (peace and blessings be upon him) said: "Whoever among you is able to benefit his brother, let him do so."

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The nations were presented to me during the Hajj season. I saw their great gathering, and their large number and their appearance (splendour) pleased me greatly, for they had filled the plain and the mountain. I was asked: O Muhammad, are you pleased? I said: Yes, O my Lord. Then Allah said: Along with these, you have seventy thousand of your Ummah who will enter Paradise without reckoning; they are those who do not seek ruqyah, do not have themselves cauterized (burned with fire as treatment), and put their trust in their Lord." Hearing this, Sayyiduna Ukkashah bin Mihsan (may Allah be pleased with him) stood up and said: O Messenger of Allah, pray to Allah to make me one of them. So he (peace and blessings be upon him) prayed for him. Then another man stood up and said: O Messenger of Allah, pray to Allah to make me one of them as well. He (peace and blessings be upon him) said: "Ukkashah has beaten you to it."
