In these days of excess entertainment and consumption, it is easy to get caught up in the so-called "holiday season", rarely stopping to consider its significance. I say so-called, because the very word holiday is derived from the two words holy and day. However, under closer scrutiny from the Judeo-Christian and Islamic perspectives, these days are anything but holy. Celebrations such as Easter, Christmas, All Saint's Day, and Halloween all find their roots in pagan traditions, alien to the prophets -may peace and blessings be upon all of them-. Proof of this lies in the lack of historical evidence that the prophets ever celebrated their birthdays, decorated eggs, placed ornaments on trees, or dressed up in costumes.
It is not proper for a Muslim to celebrate or wish Christians merry Christmas but that doesn't mean that we didn't respect their right to celebrate. They have the right to believe what they want to believe and to celebrate what they want to celebrate but is also equally important for them to respect our right not to celebrate or wish them. Obviously there will be some quarters disagree but that is individual choice and most important is to respect each other view. Whatever view you are holding to just please respecting other people who holding to a different view.
According to Islam, God neither begets nor he is begotten & the biggest abuse you can give to God is to say “He begot a son”. This is because; begetting is a lower animal function of sex which cannot be attributed to God.
According to Christianity, Jesus -peace be upon him- is god in the flesh and the only begotten son of God (I seek forgiveness from the God for saying this blasphemous statement) and Christmas is celebrated as his birthday. Since this is considered as the biggest abuse given to God, Muslims can not wish Christians on this day.
In Islam, congratulating the non-Muslims on their religious festivals is haram (forbidden) because it implies that one accepts or approves of their rituals of non-belief, even if one would not accept those things for oneself. The Muslim should not accept these rituals or congratulate anyone else for them, because the God himself does not accept any of that at all. what was not approved by the God, we do not approve.
A Christian may interpreted the condemnation of celebration of Christmas as a matter of disrespect for Christians. In reality, it is out of respect for the God almighty -glory be to him- and Jesus -peace be upon him- and the teachings of our Prophet Mohammed -peace be upon him-. It is an integral part of our faith to reject celebrations that have not been prescribed by the God, as inevitably they lead to misguidance and alterations in faith. There is nothing "radical" or "fringe" about this. It is our basic right to protect our faith and practice from distortion and falsehood. Surely no one has a right to condemn us for this.
