Al-jawab billahi at-taufeeq (the answer with Allah's guidance)
Islam does not recognise an engagement ring or a wedding ring . These are customs of the kuffaar.
Rasullulah (Sallallahu Alaihi Wa salam) has said, ""Whosoever impersonates a nation (other than Islam) will be (resurrected) from them on the day of judgment". (Sunan Abu Dawud)
