Dought & clear - She is asking aboutsome things that some people has become accustomed to doing in wedding parties.

-What is the ruling on the bunch of flowers that the bride holds?
-What is the ruling on the couple drinking juice in the wedding party?
-What is the ruling on cutting the cake of wedding party?
-What is the ruling on wearing rings for both bride and groom?
All the above mentioned things became part of the society's habits and
traditions.
Praise be to Allaah.
Islam encourages the husband to treat his wife well and to be kind to
her, especially when he enters upon her, so asto dispel any discomfort
that she may feel. Hence he is to give the virgin seven days if he
takes her as a second wife, and to give the previously-married woman
three days. He is to give (the new wife) these days before he begins
to divide his timebetween her and his other wives. All of that is
aimed as dispelling discomfort between the spouses. On the
weddingnight, Islam enjoins certain etiquette to achieve this purpose,
which includes treating the wife kindly by offering her something to
drink and the like. The great scholar al-Albaani (may Allaah have
mercy on him) said inAdaab al-Zafaaf: It is mustahabb when he enters
upon his wife to treat her kindly by offering her something to drink
and the like, because of the hadeeth of Asma' bint Yazeed who said: I
adorned 'Aa'ishah for the Messenger of Allaah(peace and blessings of
Allaah be upon him), then I went to him and invited him to look at
her, and he came and satbeside her. A large vesselof milk was brought
andhe drank some then the Prophet(peace and blessings of Allaah be
upon him) passed it to her and she lowered herhead and felt shy. Asma'
said: I rebuked her and said to her: Take (it) from the hand of the
Prophet(peace and blessings of Allaah be upon him). She said: So she
took it and drank a little, then the Prophet(peace and blessings of
Allaah be upon him) saidto her: "Give to your friend." End quote.
But what is done nowadays in wedding parties, where the husband enters
upon hisbride in the wedding party when she is with women who are not
mahrams of the husband, and he enters with all his finery and the
women are also fullyadorned, and he looks atthem and they look at him,
all of that is haraamand should be denounced. This was stated in a
fatwa by the Standing Committee for Academic Research and Issuing
Fatwas when they said: For the husband to appear on the dais beside
his wife in front of women who are not his mahrams andwho are
attending the wedding party, when hesees them and they see him, and
they are all fully adorned and wearing their best is notpermissible,
rather it is an evil which must be denounced. End quote fromFataawa
al-Lajnah al-Daa'imah li'l-Ifta'(19/120).
If what is mentioned in the question happens in the party in this
manner,then these are evils which must be avoided and warned against.
Butif that happens away from where non-mahrams can see it, then there
is nothing wrong with it in sha Allaah. But it is not permissible for
the brideor groom to wear a ring,because this is a custom that has
come to the Muslims (from others), sodoing it is an imitation of the
kaafirs. That may also be accompanied by a belief that it creates love
between the couple, and that belief isa kind of minor shirk. In
addition to that, what the man wears may be made of gold, and that
isharaam for him. We have discussed that in detail in the answer to
question no. 21441, q.v.
As for holding the hand of the bride, if what is meant is the husband
taking his wife's hand when she is holding a bunch of flowers, that is
permissible, as is also thecase if what is meant is the bride holding
a bunch of flowers in her hand during the party.
Doing the haraam thingsthat we have mentionedcannot be justified by
saying that they have become customary among some people in our
society, rather what we must do is enjoin what is good and forbid what
is evil, and combat the foreign customs that are haraam according
toour sharee'ah.
And Allaah knows best.
