Zayn was raised with a strict Muslim paternal family, and a conformed Muslim mother. While a lot of his family was strict on keeping up with traditions, the more modernized parts of his family converted to a different lifestyle. Islam still uphols various traits of pagan rituals, so December 25th in his family is not a day for the birth of Christ (whom they view as nothing more than a prophet, also realize that December 25th was a forged birth of Jesus and he is actually estimated to have been born far eariler in the year) but instead a day of celebration for the Winter Solstice and thankfulness for their family. Zayn does now put up a tree for his daughter, who was raised to find her own beliefs and recognize both religions fue to her parents, but his family has always allowed some Yule decorations and spent the day sharing their happiness together.
