Dought & clear - , She makes cards for festivals and sells them – is that permissible

I make handcrafted eid cards as a hobby and a source of income. I would like to know whether it is Bidah to dothis? 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 isthat 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 festivalsin question. If they are cards with greetings for the festivals of the kuffaar, such as Christmas, or for festivalsthat are bid’ah (innovation), such as thebirthday of the Prophet (al-Mawlid) or al-Isra’ and al-Mi’raaj, or festivals that involve imitating the kuffaar, such as national holidaysand 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 cooperatingin sin and transgression. But if they are for Islamicfestivals – and there are no Islamic festivals except Eid al-Fitr and Eid al-Adha – then it is permissible for you to make greetings cards forthem, and it is permissible for you to sell them, so long as you make sure to use phrases that are prescribed or permissible according tosharee’ah, such as “May Allaah accept from us and from you” and so on. In the answer to question no. 947 we stated that it is haraam to congratulate the kuffaar on their festivals.In the answer to question no. 782 we stated that it is haraam to sell cards for Christian festivals. In the answer to question no. 50074 wequoted the statement of the Standing Committee for Issuing Fatwas about taking part in the millennium celebrations,in which it was noted that it is not permissible to help the kuffaar in their festivals, and among the ways of helping them that the scholars mentioned are: making clothes, mementoes and cards.” In the answers to questions no. 49014 , 49021 and 36442 you willfind that it is permissibleto offer greetings on theIslamic festivals. And Allaah knows best.
