The ruling on wearing a necklace containing verses for healing from illness

Question : The questioner says: My brother was afflicted with a heart condition, so we went to a man who gave us a string with a knot in it. He claims that it contains verses and dhikr (remembrance of Allah). When he wore it, he was healed, and he advised us not to untie it. What is the ruling on this?

Answer : We say that we cannot establish that the healing that occurred was due to this knot. The healing may have been from Allah, and the tying of the knot merely delayed it as a test. Therefore, tying the knot is not a cause for healing. I see that you should remove this knot and deal with the Qur'an. I ask Allah the Exalted to restore him to health and not to repeat this affliction upon him.
