Should he let his Christian aunt stay with him so that he can call her to Islam?
Question

                At the present time I live and work in the USA and would like to know is it haraam to have my non-Muslim relitives live with me. She is my maternal anunt. She is a Christain and I have giving her du'wah but some older people can be set in their ways. Hence, what is the evidence from the Qur'aan and the Sunnah on live here with them. What if any do the scholars of this ummah say regarding this topic facing us particulaly in the USA and Britain or other non-Muslim land and we are a minority in our resisdentcy. May Allah reward you and help us to except the truth.
Praise be to Allah.
    Firstly: 

    It is permissible for you to let your aunt stay with you so 
    that you can call her to Islam and encourage her with wisdom and beautiful 
    preaching, If she sees you and your good attitude and kind treatment, that 
    may be a means of opening her heart to this great religion. Attitude and 
    actions may often be more eloquent than words and preaching. So strive hard 
    to do that, and if Allaah guides her at your hands, that will be better for 
    you than this world and everything in it.  

    You should equip yourself with patience and forbearance, and 
    respond to bad with good, and to mistakes with forgiveness, as Allaah says 
    (interpretation of the meaning): 
“The good deed and the 
    evil deed cannot be equal. Repel (the evil) with one which is better (i.e. 
    Allaah orders the faithful believers to be patient at the time of anger, and 
    to excuse those who treat them badly) then verily he, between whom and you 
    there was enmity, (will become) as though he was a close friend”

    [Fussilat 41:34]

    One of the indications that it is permissible to let a kaafir 
    stay among the Muslims, so that he may see their attitude and come to know 
    their religion, is that which is narrated concerning the story of Thumaamah 
    ibn Uthaal, who was tied up in the mosque for three days after the Muslims 
    took him prisoner. Then the Prophet  (peace and blessings of Allaah be 
    upon him) pardoned him and he became Muslim. The story is narrated in 
    Saheeh al-Bukhaari (4372) and Saheeh Muslim (1764). 

    The aunt also has kinship rights because she is a close 
    relative, even if she is a kaafir. The Prophet  (peace and blessings of 
    Allaah be upon him) said: “The maternal aunt is like the mother.” Narrated 
    by al-Bukhaari, 2700. 

    Al-Tirmidhi (3975) narrated from ‘Umar that a man came to the 
    Prophet  (peace and blessings of Allaah be upon him) and said: “O 
    Messenger of Allaah, I have committed a grievous sin; can I repent?’ He 
    said: “Do you have a mother?” He said, “No.” He said: “Do you have a 
    maternal aunt?” He said: “Yes.” He said: “Then honour her.” Classed as 
    saheeh by al-Albaani in Saheeh al-Tirmidhi. 
And he  (peace and 
    blessings of Allaah be upon him) said to Asma’: “Uphold the times of kinship 
    with your mother.” Narrated by al-Bukhaari, 2620; Muslim, 1003. And her 
    mother was a kaafir. 

    Secondly: 

    There are two basic conditions for a person to stay in a 
    non-Muslim country, as stated by the scholars. Shaykh Ibn ‘Uthaymeen (may 
    Allaah have mercy on him) said: 

    1 – He should be certain that he is able to remain strongly 
    committed to his religion, as he has enough knowledge, faith and 
    determination to remain steadfast in his religious commitment and to avoid 
    deviation and misguidance. He should bear enmity towards the kuffaar in his 
    heart and avoid taking them as friends and liking them, because doing so is 
    contrary to faith. Allaah says (interpretation of the meaning): 

    “You (O Muhammad) will not find any people who believe in 
    Allaah and the Last Day, making friendship with those who oppose Allaah and 
    His Messenger (Muhammad), even though they were their fathers or their sons 
    or their brothers or their kindred (people”

    [al-Mujaadilah 58:22]  

    “O you who believe! Take not the Jews and the Christians 
    as Awliyaa’ (friends, protectors, helpers), they are but Awliyaa’ of each 
    other. And if any amongst you takes them (as Awliyaa’), then surely, he is 
    one of them. Verily, Allaah guides not those people who are the Zaalimoon 
    (polytheists and wrongdoers and unjust).

    52. And you see those in whose hearts there is a disease 
    (of hypocrisy), they hurry to their friendship, saying: “We fear lest some 
    misfortune of a disaster may befall us.” Perhaps Allaah may bring a victory 
    or a decision according to His Will. Then they will become regretful for 
    what they have been keeping as a secret in themselves”

    [al-Maa’idah 5:51, 52]
And it is proven in 
    al-Saheehayn that the Prophet  (peace and blessings of Allaah be 
    upon him) said: “A man will be with those whom he loves.” Narrated by 
    al-Bukhaari, 6168; Muslim, 2641. 

    Loving the enemies of Allaah is one of the most serious 
    dangers that a Muslim faces, because loving them implies that one agrees 
    with them and follows them, or at the very least that he is not denouncing 
    them. 
2 – The second condition 
    is that he should be able to practise his religion openly, in the sense that 
    he can establish the rituals and symbols of Islam with no impediment, so he 
    is not prevented from establishing regular prayer, and praying Jumu’ah and 
    offering prayers in congregation if there are others with him who can pray 
    in congregation and establish Jumu’ah; and he should not be prevented from 
    paying zakaah, fasting, performing Hajj and doing all the other rituals of 
    Islam. If he is not able to do that, then it is not permissible for him to 
    stay there and he must migrate in that case. 

    End quote from Sharh al-Usool al-Thalaathah by Shaykh 
    Ibn ‘Uthaymeen (may Allaah have mercy on him), in Majmoo’ al-Fataawa, 
    6/132 
Whoever cannot meet 
    these two conditions must migrate to a Muslim land if he is able to do so. 
    If he is unable to migrate, then he is excused, because Allaah says 
    (interpretation of the meaning): 
“Verily, as for those 
    whom the angels take (in death) while they are wronging themselves (as they 
    stayed among the disbelievers even though emigration was obligatory for 
    them), they (angels) say (to them): “In what (condition) were you?” They 
    reply: “We were weak and oppressed on the earth.” They (angels) say: “Was 
    not the earth of Allaah spacious enough for you to emigrate therein?” Such 
    men will find their abode in Hell — what an evil destination!

    98. Except the weak ones among men, women and children who 
    cannot devise a plan, nor are they able to direct their way.

    99. These are they whom Allaah is likely to forgive them, 
    and Allaah is Ever Oft-Pardoning, Oft-Forgiving”[al-Nisa’ 4:97-99]
