He said to his wife: It is haraam for us to speak to one another if you go to such and such a place
Question

                Everything I do, I do it at least twice to make sure that I have done it. 

There was an argument between me and my wife because she wanted to work in a bank, and I wanted to tell her “you are like my mother if you do that” but I did not say it for fear of speaking too harshly, but I told her “It is haraam for us to speak to one another if you go there.” 

I hope that you can answer the following questions, may Allaah reward you. 

1-    Sometimes I think that I did not say the words “if you go there.” What is the Islamic ruling on either case, knowing that my intention was that if she went I would be upset with her,  i.e., I was threatening her?

2-    If I repeat my question or repeat what I said or what I am uncertain about, will I be held accountable for it? 

3-    What is the ruling on my wife’s pregnancy if there is anything haraam in what I said to her?.
Praise be to Allah.Firstly: 
From your 
    question it seems that you are suffering from waswaas, as you need to do 
    things twice and you think that you said such and such or that you did not 
    say it. 
The best 
    ways to treat waswaas are two: 
1 – Do many 
    acts of worship and remember Allaah a great deal (dhikr). 
2 – Do not 
    pay any attention to the waswasah and do not respond to it. See question no. 
    62839 and 
    25778. 
Hence we say 
    that basically what you said to your wife is, “It is haraam for us to speak 
    to one another if you go there”. So you should not pay any attention to any 
    doubts that arise because of waswasah. 
Secondly: 
If a man 
    says to his wife: “It is haraam for us to speak to one another if you go to 
    such and such a place,” if she does not go there, then he does not have to 
    do anything. 
But if she 
    does go there, the matter should be examined further. If he intended to 
    divorce her, then a divorce has taken place, because these words of his come 
    under the heading of implicit divorce. 
If he did 
    not intend to divorce her – as you say in your question – then he has to 
    offer expiation for breaking an oath (kafaarat yameen), which is freeing a 
    slave, or feeding or clothing ten poor persons. If that is not possible then 
    he must fast for three days. 
The basic 
    principle concerning that is that declaring something permissible to be 
    haraam is a kind of oath, because Allaah says (interpretation of the 
    meaning): 
“O 
    Prophet! Why do you forbid (for yourself) that which Allaah has allowed to 
    you, seeking to please your wives? And Allaah is Oft‑Forgiving, Most 
    Merciful.
2. Allaah 
    has already ordained for you (O men) the absolution from your oaths. And 
    Allaah is your Mawlaa (Lord, or Master, or Protector) and He is the 
    All‑Knower, the All‑Wise”

    [al-Tahreem 66:1-2]
So Allaah 
    describes declaring something permissible to be haraam as an oath. 
In 
    al-Bahr al-Raa’iq (4/317) it says: It is known that declaring something 
    permissible to be haraam is an oath for which expiation must be offered… 
    This includes saying “It is haraam for you to talk to me” or “talking to you 
    is haraam”. End quote. 
Thirdly: 
If a man 
    says to his wife: “It is haraam for us to speak to one another”, and he does 
    not say, “if you go to such and such a place,” if he intended to divorce her 
    then divorce has taken place in this case, whether she goes there or not. 
    But if he did not intend divorce, then he must offer expiation for breaking 
    an oath. 
Fourthly: 
If you say 
    something or ask a question, and repeat it, you do not have to do anything, 
    but it is important that the speech be permissible. 
Fifthly: 
If your wife 
    was pregnant when you said the words mentioned above, then the pregnancy 
    does not affect that. What Islam forbids is divorcing a woman when she is 
    menstruating, but if she is pregnant that does not affect the divorce, 
    although you did not actually divorce her. 
Sixthly: 
It is not 
    permissible to work in a riba-based bank because that is cooperating in sin 
    and transgression, and the Prophet  (peace and blessings of Allaah be 
    upon him) cursed the one who consumes riba, the one who pays it, the one who 
    writes it down and the two who witness it, and he said: they are all the 
    same. Narrated by Muslim (1598). 
And Allaah 
    knows best.
