‘Imraan b. Husayn (radiyallaahu ‘anhu) narrated that Allaah’s Messenger (salallaahu ‘alaihi wassallam) saw a man with wearing a brass ring. So he asked him:
“What is this?”
He responded:
“A protection from an illness that weakens.”
So the Messenger (salallaahu ‘alaihi wassallam) said:
“Remove it, for it will not increase you except in weakness. Indeed if you were to die whilst wearing it, you would never prosper.”

From this ayah and hadith we benefit that it is haraam to seek protection in something other than Allah. A silver ring is a silver ring and cannot protect you from anything. Turn back to Allah alone because He is the only One could can protect you, wallahu alim.

Allaah, the Most High, said:
قُلْ أَفَرَأَيْتُم مَّا تَدْعُونَ مِن دُونِ اللَّهِ إِنْ أَرَادَنِيَ اللَّهُ بِضُرٍّ هَلْ هُنَّ كَاشِفَاتُ ضُرِّهِ
Say, “Then have you considered what you invoke besides Allah? If Allah intended me harm, are they removers of His harm?” [az-Zumar 39:38]
أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى رَجُلًا فِي يَدِهِ حَلْقَةٌ مِنْ صُفْرٍ فَقَالَ مَا هَذِهِ الْحَلْقَةُ
قَالَ هَذِهِ مِنْ الْوَاهِنَةِ قَالَ انْزِعْهَا فَإِنَّهَا لَا تَزِيدُكَ إِلَّا وَهْنًا
