Giving gifts on Christmas is not haram in Islam. In fact, it is considered to be a kind and generous gesture. However, it is important to avoid any actions or behaviors that go against the teachings of Islam. For example, giving gifts that contain items that are forbidden in Islam, such as alcohol, pork, or gambling materials, would be considered haram. Additionally, giving gifts with the intention of showing off or seeking recognition would also be considered haram. As long as you are giving gifts out of kindness and love, it is not haram.
