He migrated to a Muslim country, then he realised that the education system is not good; can he go back to complete his studies?
Question

                My family and I lived in Canada for a long time before we came to know that migration (Hijrah) is obligatory. After we learned that, we migrated to a Muslim country, but we found that there is a great difference in the educational standards and curriculum. My father paid a great deal of money to the school in which we registered, but we found that the standard of the education system here is very low. We attended for only three days, then we left, and we thought that study is a kind of playing about and a waste of money. Now, after seeing all this, we have decided to go back to Canada to complete our studies, then we will come back to the Muslim world. Is this permissible? Please note that in Canada we let our beards grow and the women wore niqab without any problems, and we used to attend Jumu‘ah and prayers in congregation, and we used to establish Zuhr prayer in the school and attend halaqahs (study circles) in the mosque, and call people to Allah with all freedom. What is your opinion?.
Praise be to Allah.
      The ruling on migrating from kaafir countries varies 
      according to a person’s situation, his ability to migrate and his ability 
      to practice his religion openly there. 

    Hijrah is obligatory for one who is not able to practice his 
    religion openly and is able to migrate. 

    But if a person is able to practice his religion openly, it 
    is mustahabb for him to migrate (Hijrah) but is not obligatory. If a person 
    is unable to migrate, he is excused by Allah, may He be exalted. 

    Ibn Qudaamah (may Allah have mercy on him) said: 

    With regard to Hijrah, people fall into three categories: 

    1.

    Those for whom Hijrah is obligatory: this applies to the one 
    who is able to do it and is not able to practice his religion openly or 
    establish the obligatory duties of his religion if he stays among the 
    kuffaar. In this case, it is obligatory to migrate because Allah 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!”

    [al-Nisa’ 4:97].

    This is a stern warning which indicates that it is 
    obligatory. Establishing the obligatory duties of Islam is obligatory for 
    the one who is able to do that, and Hijrah is necessary for fulfilment of 
    that obligation; whatever is essential to fulfilment of an obligation is 
    also obligatory. 

    2.

    Those for whom hijrah is not obligatory. This applies to the 
    one who is not able to do it, either because of sickness, or because he is 
    forced to stay, or because of weakness in the case of women, children and so 
    on. In this case Hijrah is not obligatory, because Allah says 
    (interpretation of the meaning):

    “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’ 4:98-99].

    And it is not mustahabb for them, because it is not possible 
    for them. 

    3.

    Those for whom it is mustahabb but is not obligatory. This 
    applies to the one who is able to do it, but he is able to practice his 
    religion openly and establish it in the kaafir country. So it is mustahabb 
    for him, so that he would be able to engage in jihad against them, increase 
    the numbers of Muslims, and support them, and so that he can stop increasing 
    the numbers of kuffaar, mixing with them and seeing evil among them. But it 
    is not obligatory for him, because it is possible for him to establish the 
    obligatory duties of his religion without migrating. 

    End quote from al-Mughni, 9/236 

    Based on that, if you are able to practice your religion 
    openly as you say, then Hijrah is not obligatory for you, but moving to one 
    of the Muslim countries is better and more safe, so as to avoid increasing 
    the numbers of kuffaar, mixing with them and witnessing their evils, and so 
    as to move away from fitan (turmoils, temptations) and causes of deviation 
    which are prevalent in those societies, as well as for the sake of the 
    children who are born to the Muslims there, to save them from being lost and 
    going astray in Western societies. This applies in general, but a person may 
    be in a place in those countries where he lives among a Muslim majority and 
    is able to play his role in da‘wah, teaching and explaining Islam to others, 
    in which case it is better to him to stay and not migrate.

     So you should weigh up the pros and cons, and give priority 
    to preservation of religious commitment over other interests, for religious 
    commitment is the capital of the individual which must not be squandered. 

    With regard to going back -- temporarily -- in order to 
    obtain a better education, we hope that there is nothing wrong with you 
    doing that, especially if it is an education that you need or there is some 
    benefit to the Muslims in it, but you should keep trying to find an 
    opportunity to settle permanently in a Muslim country. 

    We ask Allah to guide and help us and you. 

    And Allah knows best.
