salam 'alikum,I can't agree at 100%
when I got engaged,my actual husband took the engage to marry me,but before doing that he gave me a ring a sign of love and to put in evidence that I was engaged,for not to allow someone else trying to be my fiancè.it remembers me good moments,it's romantic,I never put this matter under the Islamic point.the Imam who healed me told me that there was no problem if I wore a ring on the left hand(because I am able to use the right hand and it's diffucult to have rings/bracelets there),the only exception he made when he saw a ring on my left thumb,he told me not to put the ring there because it was an emulation of kafar billah.indeed evry shaikh has his truths to teach,but we have a free way to judge if it is really good or not what we are doing.Allah said not to make haram what it was halal for us.the ring as sign of engagement is first of all piece of gold/silver that our partner gave us after many hours of work and it's a satisfaction for the partner to see that on the finger,it means that they are closed to each other even if they are far.How many times I kissed my ring thinking to my beloved one?
