He set aside money for the purpose of Hijrah (migration to a Muslim country) then swore to give it in charity if he fell into sin
Question

                I am a muslim residing currently in the lands of disbelief,I was born and brought up in the west. I recently made an intention to do hijra to the lands of islam and muslims and Allah be praised and glorified, i managed to raise some money for my journey, the problem that Im facing and I pray to Allah that you can help me, is that I had a problem with a sin and everytime I committed it, I would regret it, and I would repent, but I would always go back to it and this became a big problem for me, so in order for me to stop I made an oath out of desperation, and I said " O Allah if I commit this sin again, then I will give the money which I raised to do hijra with, away in charity and I will not offer the expiation for it (kaffarat yameen). (Meaning even if I had a choice to give an expiation, I wouldnt. oblighing myself to give the money)But out of stupidity and foolishness i did it again. what can i do? should i give the money and start raising the money again or could i repent for my mistakes and head towards perparing for hijra in the way off Allah ? .
Praise be to Allah.
      You did well when you formed the intention to leave that 
      country and migrate to a Muslim country. 

    Because you were able to collect the money needed for travel, 
    but you swore that oath, intending to prevent your self from going back to 
    that sin, then you were overwhelmed by your nafs and you went back to it, 
    now you have to continue with your plan to migrate and you should not let 
    the oath that you swore hold you back. What is prescribed in the case of one 
    who swears an oath then thinks that something else is better than it, is to 
    do what is better and to offer expiation for his oath. 

    There is no doubt that the purpose of migration and the good 
    consequences that will result from it, such as keeping away from temptation 
    and its people, takes precedence over the harm caused by breaking an oath. 

    Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) 
    said: 

    The Lawgiver takes into consideration the pros and cons, and 
    when there is a  case in which there are pros and cons, the definite pros 
    take precedence over the uncertain cons. End quote. 

    Majmoo‘ al-Fataawa, 24/269 

    Al-Bukhaari (6718) and Muslim (1649) narrated from Abu Moosa 
    al-Ash‘ari (may Allah be pleased with him) that the Prophet (blessings and 
    peace of Allah be upon him) said: “By Allaah, if Allaah wills, I do not 
    swear an oath (to do something) then see something better than that, but I 
    expiate my oath and do that which is better.” 

    And Muslim (1650) narrated that Abu Hurayrah (may Allah be 
    pleased with him) said: The Messenger of Allah (blessings and peace of Allah 
    be upon him) said: “Whoever swears an oath (to do something) then sees that 
    something else is better than it, let him do that and offer expiation for 
    his oath.” 

    Al-Nawawi (may Allah have mercy on him) said: 

    In these hadeeths there is an indication that if a person 
    swears to do something or not to do something, but breaking his oath is 
    better than going ahead with it, it is mustahabb for him to break his oath 
    and he has to offer expiation for that. This is something on which there is 
    scholarly consensus. End quote. 

    So hasten to leave that land and move to a Muslim country. 
    This will be more beneficial for you and will be more effective in helping 
    you to adhere to the straight path than forcing yourself by means of oaths 
    that you are not able to fulfil. 

    You have to be sincere in repentance and turning to Allah, 
    and you have to think positively of Him and renew the covenant by coming 
    back to Him. Do not lose hope in Him, for no one who pins his hope on Allah 
    will ever be disappointed. And do not despair of the help and mercy of 
    Allah. Resolve to strive hard and turn to your Lord with a heart full of 
    fear and hope. 

    Remember the words of Allah, may He be exalted 
    (interpretation of the meaning):

    “Say: O 'Ibâdî (My slaves) who have transgressed against 
    themselves (by committing evil deeds and sins)! Despair not of the Mercy of 
    Allâh, verily Allâh forgives all sins. Truly, He is Oft-Forgiving, Most 
    Merciful[] 

    And turn in repentance and in obedience with true Faith 
    (Islâmic Monotheism) to your Lord and submit to Him, (in Islâm), before the 
    torment comes upon you, (and) then you will not be helped”

    [al-Zumar 39:53-54]. 

    You have to offer kaafarat yameen (expiation for breaking an 
    oath) for the oath that you broke, and continue with the plan of migration; 
    spend the money that you have on striving to leave that land and move to a 
    Muslim land. May Allah help you and guide you and accept your repentance. 
    And Allah knows best.
