The head of the Islamic centre in their city is married to a Christian woman; has he done something for which he deserves to be dismissed from his post?
Question

                The Amir at our Islamic Center is married to a Christian can he continue to hold the position as a religious leader for the community.
Praise be to Allah.
    Marriage of a Muslim man to a woman from the People of the 
    Book -- a Jewish or Christian woman -- is permissible in the sharee’ah of 
    Allaah, because Allaah, may He be glorified and exalted, says 
    (interpretation of the meaning):

    “Made lawful to you 
    this day are At‑Tayyibaat [all kinds of Halaal (lawful) foods, which Allaah 
    has made lawful (meat of slaughtered eatable animals, milk products, fats, 
    vegetables and fruits)]. The food (slaughtered cattle, eatable animals) of 
    the people of the Scripture (Jews and Christians) is lawful to you and yours 
    is lawful to them. (Lawful to you in marriage) are chaste women from the 
    believers and chaste women from those who were given the Scripture (Jews and 
    Christians) before your time when you have given their due Mahr 
    (bridal-money given by the husband to his wife at the time of marriage), 
    desiring chastity (i.e. taking them in legal wedlock) not committing illegal 
    sexual intercourse, nor taking them as girlfriends. And whosoever 
    disbelieves in Faith, [i.e. in the Oneness of Allaah and in all the other 
    Articles of Faith i.e. His (Allaah’s) Angels, His Holy Books, His 
    Messengers, the Day of Resurrection and Al‑Qadar (Divine Preordainments)], 
    then fruitless is his work; and in the Hereafter he will be among the losers”

    [al-Maa’idah 5:5]. 

    The woman of the People of the Book whom it is permissible to 
    marry is the one who is chaste. 

    See the answer to question number
    2527. 

    Secondly: 

    The Prophet (blessings and peace of Allaah be upon him) 
    commanded men to choose as wives those who are religiously committed and of 
    good character. The Prophet (blessings and peace of Allaah be upon him) 
    said: “Choose the one who is religiously-committed, may your hands be rubbed 
    with dust (i.e., may you prosper).” Narrated by al-Bukhaari (5090) and 
    Muslim (1466). Hence many of these scholars are of the view that it is 
    makrooh for a Muslim to marry a woman of the People of the Book. They have 
    other reasons for regarding this as makrooh, including the following: 

    1.Their fear of marrying one who 
    is not chaste

    It was narrated that Shaqeeq ibn Salamah said: Hudhayfah 
    married a Jewish woman, and ‘Umar wrote to him saying: Let her go. He wrote 
    to him saying: Are you saying that she is haraam so that I should let her 
    go? He said: I am not claiming that it is haraam; rather I am worried lest 
    you marry the immoral ones among them. Narrated by Ibn Jareer al-Tabari in 
    his Tafseer, 4/366; classed as saheeh by al-Haafiz Ibn Katheer in his
    Tafseer, 1/583 

    2.Their fear that the Muslims 
    will begin to marry women of the People of the Book and the Muslim women 
    will be left without husbands

    It was narrated from ‘Aamir ibn ‘Abd-Allaah ibn Nastaas that 
    Talhah ibn ‘Ubayd-Allaah married the daughter of the Jewish leader and he 
    said: ‘Umar insisted that he should divorce her. This was narrated by ‘Abd 
    al-Razzaaq in al-Musannaf, 6/79. 

    Ibn Jareer al-Tabari (may Allaah have mercy on him) said, 
    commenting on what ‘Umar said to Hudhayfah and Talhah: 

    Rather ‘Umar objected to Talhah and Hudhayfah (may Allaah 
    have mercy on them) marrying the Jewish and Christian women lest the people 
    follow their example in that, and lose interest in the Muslim women, or for 
    other similar reasons, so he commanded them to let them go. End quote. 

    Tafseer al-Tabari, 4/366 

    3.Many negative consequences that 
    may result from such marriages, such as disputes and arguments and dangers 
    posed to the religious commitment and beliefs of the children

    We have mentioned the negative consequences of marriage to 
    women of the People of the Book in the answer to question number
    20227; please read this as it 
    is important. 

    Thirdly: 

    The scholars (may Allaah have mercy on them) mentioned a 
    principle, namely that that which is makrooh is permissible if the Muslim 
    needs it. 

    See this principle and others in Sharh Manzoomat Usool 
    al-Fiqh wa Qawaa’iduhu  by Shaykh Ibn ‘Uthaymeen, p. 62. 

    Based on that, what the head of the Islamic centre has done 
    is makrooh in principle, but we cannot state that this particular person has 
    done something that is makrooh in his particular case, because he may have 
    reasons for that which mean that it cannot be judged to be makrooh. 

    If we assume that he has done something makrooh, then he has 
    not done something haraam; rather he has done something which the Qur’aan 
    indicates is permissible. 

    Such matters do not mean that he is no longer regarded as 
    being a man of good character, and do not mean that he must be shunned or 
    dismissed from his post, because he has not done something haraam, and it 
    does not affect his good character and trustworthiness. Be kind to him and 
    be united, especially in your country, where you are in great need of being 
    united and building ties with one another. 

    And Allaah knows best.
