Ruling on amulets

Q 7: A man wrote only some Ayahs (Qur'anic verses) on a piece of paper for a sick person and told him: "When you return home, hammer a nail into every word of these Ayahs as Alif-Lâm-Mîm. [These letters are one of the miracles of the Qur’ân and none but Allâh (Alone) knows their meanings.] This is the Book (the Qur’ân), whereof there is no doubt He pronounces some words upon the letter "A" (Alif) and then hammers it with a nail and so on. Then, he conceals this paper for ten or fifteen days. Is this a kind of Shirk (associating others with Allah in His Divinity or worship)? Is this considered a kind of amulet? Is it permissible to do so?

A: It is not permissible to do this as it is one kind of amulets that the Prophet (peace be upon him) forbade. He (peace be upon him) said: Anyone who wears an amulet, may Allah not fulfill it (i.e., his want) for him, and anyone who wears a sea-shell, may Allah not give him peace. It was said in another narration: Anyone who wears an amulet commits an act of Shirk. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and his Companions.
