Dought & clear, - She swore that she would not eat from theirwealth unless they stopped dealing with bonds concerning which the scholars differed.- visit-http://aydnajimudeen.blogspot.com

I live in a gulf country. People here started dealing with what is
called (national cheques) and are saying that it is halal. So I
started using them as well as my family did. Some time after this some
scholars (including the mufti of one of the emirates) said it includes
Islamic restriction and they informed the Islamic bank about them but
the bank did not fully investigate.
So now these cheques are disagreed upon some say it is halal while
others say it is haram. When I knew this I told my family that I want
to withdraw from such transactions and I have already withdrawn
Alhamdulillah. I advised my family to withdraw theirs but they did not
respond to me. I swore that I would not even drink a cup of water if
they win any extra amount and I repeated my oath in different
occasions, not at the same time. What shall I do? How shall I expiate?
Is it permissible for me to eat from what is made of this money? I
really do not want to even drink water which is bought by this money,
what shall I do? Please answer me. I am a girl and I cannot live
alone.
Praise be to Allaah.
Firstly:
The one who wants to engage in some transaction with a company or
anyone else must know the rulings on that, and find out whether it is
Islamically acceptable, either by researching it himself or asking the
scholars, as Allaah says (interpretation of the meaning):"So ask of
those who know the Scripture, if you know not" [al-Nahl 16:43].
If you subscribed to these bonds following a fatwa issued by a
trustworthy scholar which said that they are permissible, then there
is no sin on you.
If a person is sure that they are haraam, then it is not permissible
for him to subscribe to them. If a person subscribes to them then
finds out that they are haraam, then he must get out of it, and there
is no sin on him for what happened in the past.
You have done well to get out of it and withdraw your money. This is
safer and better.
Secondly:
If your family do not think that they are haraam, then they do not
have to get rid of these bonds, because they followed the fatwa of one
who said they are permissible. If they are not qualified to know the
difference and determine what is more correct, and they rely on
following a scholar whom they trust, there is no blame on them.
Thirdly:
It is permissible for you to eat and drink food and drink offered to
you by your family, because their wealth is mixed, and because wealth
that is haraam because of the manner in which it is acquired is haraam
only for the one who acquires it and not others who take it from him
by permissible means. See the answer to question no. 45018.
With regard to your oath, if you wish you may adhere to it, and not
benefit from anything that results from the profits of these bonds,
whilst benefiting from their other wealth, or if you wish you may
offer expiation for breaking your oath.
You only have to offer expiation once, because the one who swears
repeated oaths concerning the same thing only has to offer expiation
once in the event of breaking the oath. And Allaah knows best.
