No, Muslims do not celebrate Christmas. Christmas is a holiday celebrated by Christians as the birth of Jesus Christ, the son of God. Muslims believe that Jesus was a great prophet, but they do not believe he was the son of God. Muslims also do not celebrate Easter, which is the holiday that commemorates the resurrection of Jesus. Instead, Muslims celebrate two major holidays, Eid al-Fitr and Eid al-Adha, which commemorate important events in the life of the Prophet Muhammad.
