Abdullah bin Abbas reported,

Dimad came to Mecca. He was from Azd Shanuah and used to recite incantations to treat this kind of madness. He heard some foolish people of Mecca saying that Muhammad was insane, so he said, "If only I could see this man, perhaps Allah might cure him through my hands."He met him and said, "Muhammad, I recite incantations for this kind of affliction, and Allah cures whomever He wills through my hands. Would you like that?"The Messenger of Allah ﷺ said, "All praise belongs to Allah. We praise Him and seek His help. Whomever Allah guides, none can lead astray, and whomever He leads astray, none can guide. I bear witness that there is no god but Allah alone, with no partner, and that Muhammad is His servant and messenger. Now then..."Dimad said, "Repeat these words of yours to me." So the Messenger of Allah ﷺ repeated them to him three times.Dimad said, "I have heard the words of soothsayers, the words of magicians, and the words of poets, but I have never heard anything like these words of yours. They reach the very depths of the ocean. Give me your hand so I may pledge allegiance to you upon Islam."So he pledged allegiance to him. The Messenger of Allah ﷺ said, "And on behalf of your people as well."Dimad said, "And on behalf of my people."The Messenger of Allah ﷺ later sent out a raiding party, and they passed by Dimad's people. The leader of the party said to the troops, "Have you taken anything from these people?"A man from the group said, "I took a water vessel from them."He said, "Return it, for these are the people of Dimad."

عن ابن عباس

أن ضمادا قدم مكة وكان من أزد شنوءة وكان يرقي من هذه الريح فسمع سفهاء من أهل مكة يقولون إن محمدا مجنون فقال لو أني رأيت هذا الرجل لعل الله يشفيه على يدي قال فلقيه فقال يا محمد إني أرقي من هذه الريح وإن الله يشفي على يدي من شاء فهل لك فقال رسول الله ﷺ إن الحمد لله نحمده ونستعينه من يهده الله فلا مضل له ومن يضلل فلا هادي له وأشهد أن لا إله إلا الله وحده لا شريك له وأن محمدا عبده ورسوله أما بعد قال فقال أعد علي كلماتك هؤلاء فأعادهن عليه رسول الله ﷺ ثلاث مرات قال فقال لقد سمعت قول الكهنة وقول السحرة وقول الشعراء فما سمعت مثل كلماتك هؤلاء ولقد بلغن ناعوس البحر قال فقال هات يدك أبايعك على الإسلام قال فبايعه فقال رسول الله ﷺ وعلى قومك قال وعلى قومي قال فبعث رسول الله ﷺ سرية فمروا بقومه فقال صاحب السرية للجيش هل أصبتم من هؤلاء شيئا فقال رجل من القوم أصبت منهم مطهرة فقال ردوها فإن هؤلاء قوم ضماد
