She makes cards for festivals and sells them – is that permissible

Reading
Quran online

I make handcrafted eid cards as a hobby
and a source of income. I would like to know whether it is Bidah to do
this? I have been told that everything is halal unless it has been
specifically made haram. Please help as this is the time of year that
people buy the cards from me and I really need to know whether I am
doing something wrong.



Praise be to Allaah.

Yes, the basic principle is that transactions are permitted and allowed, and it is
not permissible to describe anything as haraam except with evidence. The
ruling on the cards that you make for festivals varies according to the
festivals in question. If they are cards with greetings for the festivals of
the kuffaar, such as Christmas, or for festivals that are bid’ah
(innovation), such as the birthday of the Prophet (al-Mawlid) or al-Isra’
and al-Mi’raaj, or festivals that involve imitating the kuffaar, such as
national holidays and birthdays, then it is not permissible for you to make
them or sell them, and it is not permissible for anyone to buy them, because
that implies approval of those festivals that go against Islam, and because
it is cooperating in sin and transgression. 

But if they
are for Islamic festivals – and there are no Islamic festivals except Eid
al-Fitr and Eid al-Adha – then it is permissible for you to make greetings
cards for them, and it is permissible for you to sell them, so long as you
make sure to use phrases that are prescribed or permissible according to
sharee’ah, such as “May Allaah accept from us and from you” and so on. Read

of helping them that the scholars mentioned are: making clothes, mementoes
and cards.”
