No, Christmas is not considered haram in Islam. Christmas is a Christian holiday that celebrates the birth of Jesus Christ, but it is also a time for people of all faiths to come together and celebrate the spirit of giving and generosity. It is a day of peace and goodwill, and it is a time to reflect on the values of love, compassion, and understanding. So, while Christmas is not a holiday that is specifically mentioned in the Quran, it is not considered haram in Islam.
