Should she appoint a company to do Hajj on her behalf when she does not know whether they will do the rituals as they should be done or not?
Question

                I have an incurable illness, the cause of which is not known, and there is no way to treat it up till now. I heard that in Makkah there is a company that will cooperate with another company in Egypt to do Hajj and ‘Umrah on behalf of those who have passed away and those who are sick. But I am not really sure whether they will do Hajj and ‘umrah on our behalf or not.

Should I send them money, even if I am not sure about them?

Will I be rewarded and will my Hajj be complete if this is not real, or would I still not yet have done the obligatory Hajj?

Can I send someone to do ‘Umrah or Hajj more than once, or is appointing someone to do Hajj and ‘Umrah on my behalf something that can only be done for the obligatory Hajj and ‘Umrah?
Praise be to Allah.
    Firstly: 

    We ask Allah the Almighty, Lord of the 
    mighty Throne, to heal you of your sickness by His grace, generosity and 
    kindness, a healing that leaves no sickness behind. 

    To proceed: 

    If a person is sick with an illness for 
    which there is no hope of a cure (and which prevents him from doing Hajj), 
    then he may appoint someone else to do the obligatory Hajj on his behalf, on 
    condition that the proxy has already done Hajj for himself. 

    Please see the answers to questions no.

    Secondly: 

    The basic principle with regard to these 
    companies that do Hajj and ‘Umrah on behalf of others is that they are to be 
    trusted, because trust is a basic factor in their continuing to operate, and 
    they are keen for their companies to keep going. The people involved in any 
    project are usually very keen to do their work properly so that people will 
    come to them and will not think badly of them, thus shunning them and going 
    to someone else. This is the least that can be said with regard to the basic 
    principle. 

    Nevertheless, you should be careful with 
    regard to your acts of worship and strive hard to discharge your duty 
    properly (by making sure that everything is in order), and you should not 
    rely in such matters on anyone except people who you know or think most 
    likely will do the job properly, either because you know that from 
    experience or you have heard that from trustworthy people who know the 
    persons involved. 

    Then if you have tried your hardest in 
    that regard and you think it most likely that the proxy is trustworthy, then 
    you do not have to examine him closely and find out if he has fulfilled the 
    trust or not, because the basic principle is that he will do it, especially 
    with regard to acts of worship, unless you see something about him that 
    gives rise to doubts concerning him. 

    Shaykh Ibn Baaz (may Allah have mercy on 
    him) said: 

    The basic principle is that in such 
    matters the one who takes it upon himself will usually do it. This is what 
    usually happens; there may some cases where trust is betrayed, but in most 
    cases the proxy will do it. But if a person wants to be on the safe side and 
    does another Hajj, that is better, and it comes under the heading of the 
    hadith “Leave that which makes you doubt for that which does not make you 
    doubt” and is safer. End quote.

    Whatever the case, we do not advise you to 
    deal with such companies of which you do not know anything and of which no 
    trustworthy person who knows about them has told you anything good. 

    We know that in every country and in every 
    place there are people one knows who are residents or travellers to that 
    country who could do these things on your behalf, so try hard to look among 
    those around you or those whom you know for someone whom you can appoint as 
    your proxy to do that on your behalf, or who can appoint a trustworthy 
    person who is able to do that. 

    Thirdly: 

    If the sick person appoints someone to do 
    Hajj or ‘Umrah on his behalf, then he should appoint someone who is 
    trustworthy and knows how to do the rituals; he should not appoint someone 
    who is not trustworthy or is ignorant. 

    If he appoints someone then it becomes 
    clear that he is not trustworthy, then if he appointed him to do the 
    obligatory Hajj and it turned out that he did not do the rituals as they 
    should be done, and he was careless in carrying out what he had been 
    appointed to do, then the proxy is liable for the costs of this Hajj, 
    meaning that he (the one who appointed him) may ask him to pay for the cost 
    of this Hajj, and it should be taken from him, then he (the one who 
    appointed the proxy) appoint someone else who is trustworthy and knows how 
    to do the rituals, to perform Hajj on his behalf the following year. 

    If he appointed him to do voluntary Hajj, 
    then it turned out that he was not trustworthy and did not do the rituals as 
    they should be done, then he (the proxy) is liable but the one who appointed 
    him does not have to make arrangements for another Hajj on his behalf the 
    following year. 

    Shaykh Ibn Baaz (may Allah have mercy on 
    him) was asked: 

    There is a person who gave some money to 
    someone to do Hajj on behalf of his mother, and he thought that he was 
    trustworthy, then it turned out that this person was involved in things that 
    are not right, and he is asking what he should do. 

    He replied:

    The one who wants to appoint someone else 
    to do something on his behalf has to look for that person and find out 
    whether he is trustworthy and righteous. If the Hajj was obligatory, he has 
    to make up for it by doing another Hajj. If the Hajj was in fulfilment of a 
    person’s last wishes, with the costs to be paid from his estate, and he (the 
    heir) gave that task to someone who was not trustworthy, then to be on the 
    safe side he should do it again, because he was not careful; rather he was 
    heedless. But if it was a voluntary or recommended Hajj, and there was no 
    final instructions from someone who passed away – rather he wanted to do a 
    voluntary deed and earn the reward – then he does not have to do anything, 
    although if he wants to do it again, there is nothing wrong with that.

    Fourthly: 

    The scholars differed with regard to doing 
    a voluntary Hajj or ‘Umrah by proxy. Some of them regarded that as 
    permissible, if the one who appoints the proxy is unable to do it because of 
    old age or sickness for which there is no hope of a cure, and the proxy has 
    already done the obligatory Hajj on his own behalf. This is the view 
    favoured by the scholars of the Standing Committee and by Shaykh Ibn Baaz 
    (may Allah have mercy on him). 

    Others are of the view that this is not 
    allowed, and this is the well-known view of Shaykh Ibn ‘Uthaymeen (may Allah 
    have mercy on him).

    Shaykh Ibn ‘Uthaymeen (may Allah have 
    mercy on him) issued a fatwa in which he granted a concession allowing a son 
    to do a voluntary Hajj on behalf of his father, at the father’s request. 

    He (may Allah have mercy on him) was 
    asked: 

    My father has asked me to do Hajj on his 
    behalf this year, a voluntary Hajj, because he did Hajj once. He is 
    financially able to do Hajj, but is physically unable due to poor health. 
    Can I do Hajj on his behalf, knowing that I have already done Hajj for 
    myself? 

    The shaykh replied: There is nothing wrong 
    with doing Hajj on his behalf in this case.
