Is It Prohibited to Have a Christmas Tree?
Question

I don’t celebrate Christmas in any way but my 11 year old daughter loves the beauty of a Christmas tree when decorated. Is it permissible for me to have one in my house throughout the year?
Praise be to Allah.Is it prohibited to have a Christmas tree?
The Christmas tree is one of the symbols of the Christian festival and celebration; this is why it is named for Christmas . It is said that it was first officially used as a symbol in this manner in the sixteenth century in Germany, in the Cathedral of Strasbourg in 1539 CE. 
It is not permissible to imitate the non-Muslims in any of their acts of worship, rituals or symbols. The Prophet (blessings and peace of Allah be upon him) said: “Whoever imitates a people is one of them.” (Narrated by Abu Dawud, 4031; classed as authentic by Al-Albani in Irwa’ Al-Ghalil, 5/109)
So, it is not permissible to put up this tree in a Muslim house even if you do not celebrate Christmas , because putting up this tree comes under the heading of imitating others which is prohibited, or venerating and showing respect to a religious symbol of the non-Muslims.
What should Muslim parents teach their children about the Christmas tree?
Parents must protect their children and keep them away from what is prohibited,  and protect them from the Fire as Allah, may He be Exalted, says (interpretation of the meaning)”
“O you who believe! Ward off yourselves and your families against a Fire (Hell) whose fuel is men and stones, over which are (appointed) angels stern (and) severe, who disobey not, (from executing) the Commands they receive from Allah, but do that which they are commanded.” [At-Tahrim 66:6]
It was narrated from Ibn `Umar (may Allah be pleased with him) that the Prophet (blessings and peace of Allah be upon him) said: “Each of you is a shepherd and each of you is responsible for his flock. The ruler of the people is a shepherd and is responsible for his flock. A man is the shepherd of his household and is responsible for his flock. A woman is the shepherd of her husband’s house and children and is responsible for her flock. The slave is the shepherd of his master’s wealth and is responsible for it. Each of you is a shepherd and each of you is responsible for his flock.” (Al-Bukhari, 7138; Muslim, 1829) 
Al-Bukhari (7151) and Muslim (142) also narrated that Ma`qil ibn Yasar Al-Muzani (may Allah be pleased with him) said: I heard the Messenger of Allah (blessings and peace of Allah be upon him) say: “There is no person whom Allah puts in charge of others, and when he dies he is insincere to his subjects, but Allah will forbid Paradise to him.” 
You should explain to your daughter that it is prohibited to imitate the disbelievers and that it is obligatory to differ from those who are doomed to Hell and to dislike what they venerate of clothing, symbols or rituals, so as to develop respect for her own religion and adhere to it, practising the principle of loyalty and friendship as opposed to disavowal and enmity (Al-Wala’ wal Bara’) which is one of the cornerstones of Tawhid and one of the basic principles of faith.
