To wear a Ring, Twine, or anything similar to them for prevention or lifting of Harm or Affliction, is an act of Shirk!

Allah the Almighty said:

“Say: Tell me then, the things that you invoke besides Allah, -if Allah intended some harm for me, could they remove His harm, or if He (Allah) intended some mercy for me, could they withhold His Mercy? Say: Sufficient for me is Allah; in Him those who trust (i.e. believers) must put their trust.” (39:38)

Imran bin Husain (رضي الله عنه) narrated:

The Prophet (ﷺ) once saw a man with a brass ring on his hand and asked him, “What is this?” The man replied, “To overcome the weakness of old age.” He said, “Remove it, for, it can only add to your weakness. Should death overtake you while you are wearing it, you would never succeed.”

[This Hadith was recorded by Ahmad (bin Hanbal) (May Allah be pleased with him) with a good chain of narrators.]

He also recorded a Marfu’ Hadith; Uqbah bin Aamir (رضي الله عنه) narrated that Prophet Muhammad (ﷺ) said:

“Whoever wears talisman or an amulet would never see his wish fulfilled by Allah. And whoever hangs a sea shell would never get peace and rest.”

In an another version the Prophet (May the peace and blessing of Allah be upon him) is reported to have said:

“Whoever wears a talisman has committed Shirk (polytheism).”

Ibn Abi Hatim reported about Hudhaifah (رضي الله عنه):

He saw a man with a piece of twine on his hand (as a protection or cure from fever) so he cut the twine and read the verse: “Most of them believe in Allah and still practise Shirk (polytheism).” (12: 106)

Ahl Al-Bid’ah amongst the Jinn

Al-Hâfidh Ibn Kathîr – Allâh have mercy upon him – reports the following incident in his tafsîr of Sûrah Al-Jinn, verse 11:

Ahmad b. Sulaymân al-Najjâd said in his Amâlî: … Abû Mu’âwiyah said, “I heard Al-A’mash say, ‘A jinni once came to us and I asked him: what is the favorite food amongst you?’ He replied, ‘Rice.’ So we gave some to them and I saw handfuls of rice being lifted and I couldn’t see anyone [picking them up]. I asked, ‘Do these false desires (bid’ah) that are amongst us exist amongst you?’ He replied, ‘Yes.’ I asked, ‘How are the Râfidah amongst you?’ He replied, ‘The worst of us.’”

Ibn Kathîr said, ‘I presented this chain of narration to our Shaykh, Al-Hâfidh Abû Al-Hajjâj Al-Mizzî and he said, ‘This chain of narration issahîhall the way to Al-A’mash.’’
