The practice of wearing a Dublah, for a man or a woman, is an innovated practice, and perhaps it is unlawful. This is because some people wear it believing that it causes love to last between the husband and the wife. We have been told that some women inscribe their husband's name on it and the husband does the same for her, in the hope that it will make their love last. This is a form of Shirk because believe that something is a means that Allaah Almighty has not made a means, neither from the view of it's abilities, nor from the Shari'ah view.
For what is the relationship between this Dublah and between love and affection? How many men and women who don't wear the Dublah have a more lasting relationship than those who do.
And how many men and women who wear the Dublah live in misery and bitterness?
Therefore, with this false belief it is a kind of Shirk. Without this belief, it remains a practice that resembles that of non-Muslims. This is because this Dublah is taken from the Christians, and in this regard it is obligatory for the believer to stay away from everything that would blemish his religion.
However, if a man wears a silver ring without the ideas related to a Dublah, i.e., that unites him to his wife, but simply as a ring, then there is no harm in this. Because men are allowed to wear rings made of silver. It is gold rings that they are forbidden from, for the Prophet (sallAllaahu `alayhi wa sallam) saw one of his Companions wearing a ring on his hand, so he discarded it and said:
يعمد أحدكم إلى جمرة من نار فيجعلها في يده
"One of you takes to an ember from the Fire and then wears it on his hand." (Muslim no. 2090)
