Woman in ‘iddah moving to another land because she fears for her life
Question

                A woman’s husband in Baghdad was killed because his name was “Umar”, and they took his home. Her husband’s family wants to move to Syria taking her children with them. Is it permissible for her to go with them, or she has to complete the ‘iddah of her husband’s death in Baghdad? Knowing that she fears for herself and her children.
Praise be to Allah.
    Firstly: 

    We ask Allaah to cause Islam and its people to prevail, and 
    to make things easier for our brothers in Iraq, and to be kind to them, and 
    to console their broken hearts, for He is able to do that.

     We ask Allaah to restrain the evil of those hypocrites who 
    transgress against our Muslim brothers and cause their plots to backfire, 
    and to send upon them His punishment which no one can prevent from befalling 
    the evildoers.  

    Secondly: 

    The basic principle is that a woman should observe ‘iddah in 
    the house in which news of her husband’s death came to her, because of the 
    report narrated by the authors of al-Sunan, that the Prophet SAWS 
    (peace and blessings of Allaah be upon him) said to Furay’ah bint Maalik: 
    “Stay in the house in which the news of your husband’s death came to you, 
    until your ‘iddah is over.”  Abu Dawood (2300), al-Tirmidhi (1204), 
    al-Nasaa’i (200) and Ibn Majaah (2031); classed as saheeh by al-Albaani in
    Saheeh Sunan Ibn Majaah. 

    But if she fears for her life by staying there, because of 
    the presence of an enemy and so on, then it is permissible for her to move 
    and observe her ‘iddah in another place or another land. 

    Ibn Qudaamah (may Allaah have mercy on him) said: Among those 
    who regarded it as obligatory for a newly-widowed woman to observe ‘iddah in 
    her house were ‘Umar and ‘Uthmaan (may Allaah be pleased with them). That 
    was also narrated from Ibn ‘Umar, Ibn Mas’ood and Umm Salamah, and it was 
    the view held by Maalik, al-Thawri, al-Awzaa’i, Abu Haneefah, al-Shaafa’i 
    and Ishaaq. Ibn ‘Abd al-Barr said: This was also the view of a number of 
    fuqaha’ in the regions, in Hijaaz, Syria and Iraq. 

    Then he said: If she fears the collapse (of her house) or 
    drowning or an enemy and so on, then she may move, because she is excused in 
    that case … and she may live wherever she wants. End quote from al-Mughni 
    (8/127). 

    The Scholars of the Standing Committee for Issuing Fatwas was 
    asked: What is the ruling on a woman whose husband dies in her home and she 
    wants to complete her ‘iddah in another city because there is no one who can 
    take care of her affairs in the city where her husband died? 

    They replied: 

    If the situation is as described and she has no one in the 
    city where her husband died who can take look after her affairs, and she 
    cannot look after her own affairs, then it is permissible for her to move to 
    another city where she can be safe  and can find someone to look after her 
    affairs. End quote from Fataawa al-Lajnah al-Daa’imah (10/463). 

    It also says (20/473): If your newly-widowed sister moves 
    from the marital home to another house during the 'iddah because of some 
    essential need, such as if she fears for her life by staying there alone, 
    then there is nothing wrong with that, and she may complete her ‘iddah in 
    the house to which she moved. End quote. 

    Based on that, there is nothing wrong with this woman moving 
    to Syria and completing her ‘iddah there. 

    And Allaah knows best.
