Answer: 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 Allah 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:
“One of you takes to an ember from the Fire and then wears it on his hand.” (Muslim no. 2090)
[Shaykh Muhammad ibn Saalih al-`Uthaymeen – Fatawa Islamiyah, Vol. 7, Pages 391-392 – Darussalaam]
Ruling on Wearing Engagement and Wedding Rings
Praise be to Allah.
With regard to men wearing gold, whether it is a ring or anything else, it is not permissible under any circumstances, because the Prophet (peace and blessings of Allah be upon him) forbade gold for the males of this Ummah. He saw a man wearing a ring of gold and he (peace and blessings of Allah be upon him) took if from his hand and said, “Would any one of you take a coal from the fire and hold it in his hand?” (Narrated by Muslim, al-Libaas wa’l-Zeenah, 3897). So it is not permissible for the Muslim male to wear a gold ring. But with regard to rings of silver or any other kind of metal, it is permissible for men to wear them even if they are precious metals.
With regard to the wedding ring, which is worn on the occasion of marriage, this is not one of the customs of the Muslims. If it is believed that it generates love between the spouses, and that taking it off and not wearing it will have an effect on the marital relationship, then this is regarded as a form of shirk and is a kind of jaahili belief. Based on the above, it is not permissible to wear a wedding ring under any circumstances.
Firstly, because it is an imitation of those who are no good; it is a custom that has come to the Muslims from the non-Muslims.
Secondly, if that is accompanied by the belief that it has an effect on the marital relationship, then this is a kind of shirk. Laa hawla wa laa quwwata illa Billaah (there is no power and no strength except with Allah).
[From a fatwa issued by Shaykh Saalih al-Fawzaan]
Shaykh Ibn ‘Uthaymeen (rahimahullah) was asked about the ruling on wearing engagement rings. He said: The engagement ring is a kind of ring, and there is nothing wrong with rings in principle, unless that is accompanied by some belief, as some people do when the man writes his name on the ring that he gives to his fiance, and she writes her name on the ring that she gives to him, believing that this will create strong bonds between the couple. In this case, this ring is haram, because it is an attachment to something for which there is no basis in Islam and which makes no sense. Similarly, with regard to the engagement ring, it is not permissible to the man to put it on his fiance’s hand, because she is not his wife yet and she is still a stranger (non-mahram) to him, because she is not his wife until after the marriage contract has been done.
[See al-Fataawa al-Jaami’ah li’l-Mar’ah al-Muslimah, vol. 3, p. 914-915]
The Ruling on Engagement Rings
By: Shaykh Muhammad ibn Haadee al-Madkhalee
Question: This person asks about wearing a ring; i.e., at the time of the proposal for marriage.
Answer: It is not permissible for you. This is blind following of the disbelievers. It was not known amongst the people of al-Islam. It has only come from the disbelievers. It has only come from the disbelievers. So it is not permissible for you to do that. They believe that when you put it on her then the marital life has commenced between the two of you; this is it origin. And it is based upon their Trinitarian belief. They pass it over the fingers then they put it in its place.  So the Muslim is to distance himself from imitation of the disbelievers. There has already come with us yesterday, or before yesterday (the Hadeeth):
He who imitates a people then he is from them.
[Shaykh Muhammad ibn Haadee al-Madkhalee (hafidhahullaah): Translated by: Raha ibn Donald Batts (Masjid Tawheed wa Sunnah): Source]
 Note: In the Eastern Orthodox Service of Betrothal, the Priest makes the Sign of the Cross with rings over the bridegroom’s head while saying three times “The servant of God (Groom) is betrothed to the handmaid of God (Bride), in the Name of the Father, and of the Son, and of the Holy Spirit. Amen”. This is then followed by another three times over the bride’s head with the names reversed, after which the rings are exchanged three times (either by the priest or by the best man). The Priest asks God “to bless this putting on of rings with a heavenly blessing and that an Angel of the Lord will go before these Your servants, all the days of their life.” In Eastern Orthodox tradition the wedding ring is worn on the right hand rather than the left.

During the yester years in medieval England, bridegroom would slide the ring part-way up his bride’s thumb, index and middle finger, saying “In the name of the father, the son, and the holy ghost” as he passed each one. He then put the ring on the next available finger i.e. third finger of left hand. It was in 1500s that the practice was finally formalized, when Henry VIII’s son wrote the book ‘The Book of Common Prayer’. The book spelt English modern Protestant wedding vows and verdict on the finger on which the wedding rings should be worn. (Source)
