Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) used to narrate: A man named Dhamad, who belonged to Azd Shanu’ah, came to Makkah. He used to perform ruqyah (spiritual healing) for madness (i.e., mental illness). The foolish people of Makkah used to say: Muhammad (peace be upon him) has been afflicted with madness. This man said: If I see this person, perhaps Allah Almighty will grant him healing through me. The narrator says: He met the Prophet (peace be upon him), and he said: O Muhammad (peace be upon him), I perform ruqyah for this madness (i.e., mental imbalance), and Allah Almighty grants healing through me to whomever He wills, so do you have any interest in this? The Prophet (peace be upon him) said:“Indeed, all praise is due to Allah alone. We praise Him, and seek help from Him. Whomever Allah guides, none can misguide, and whomever He lets go astray, none can guide. I bear witness that there is no deity except Allah, He is One, He has no partner, and Muhammad (peace be upon him) is His servant and His Messenger. To proceed.”The man said: Repeat these words of yours to me again. So the Prophet (peace be upon him) repeated these words to him three times. The man said: I have heard the words of soothsayers, I have heard the words of magicians, I have heard the words of poets, but I have never heard any words like yours. Extend your hand so that I may pledge allegiance to Islam at your blessed hand. The Prophet (peace be upon him) said: Will your people also do so? He said: My people will also do so. The narrator says: So the Prophet (peace be upon him) took the pledge of allegiance from him. Then the Prophet (peace be upon him) dispatched a military expedition. They passed by a certain tribe, so the commander of the army said to his army: Have you taken anything from these people? One of those present said: I have taken a water vessel from them. The commander said: Return it to them, for these are the people of Dhamad’s tribe.
