Christmas is not considered to be haram by most Muslims. While there are some sects of Islam that may have different beliefs, the majority of Muslims believe that Christmas is a time for celebration and joy. Some Muslims may choose not to participate in certain Christmas traditions, such as decorating a Christmas tree, but it is not considered to be haram or forbidden. Instead, it is seen as a time to reflect on the birth of Jesus Christ and the message of peace and love that he represents.
