Should he stop his wife from listening to misguided du'at?
Question

                I have proposed to a religious girl. The problem is that I found that there are some things she is ignorant of. Also some of the scholars she wants to listen to are of those who are called (satellite preachers). Many scholars have warned from listening to such preachers. Other scholars she listens to are of those who care about satisfying the government. They sometimes criticize Ahlus-Sunnah, or say things like ‘women are allowed to be judges and presidents’. 

I said to her that I cannot let her listen to a scholar who spreads innovations or a non-knowledgeable person; because it is my responsibility in front of Allah to guard her from such things. She sees this as dominating, and says that I do not trust that she can distinguish between what is right and what is wrong. She also says that the scholars she listens to are saying good things. Am I mistaken? Or it is my right and even duty to protect her?
Praise be to Allah.A man has to strive to 
    guide his wife and encourage her to do the duties that Allah has enjoined 
    as much as he can, because Allah says (interpretation of the meaning): 
“O you who believe! Ward 
    off yourselves and your families against a Fire (Hell) …”
[al-Tahreem 66:6] 
The great scholar Abu Bakr 
    al-Jassas (may Allah have mercy on him) said in Ahkam al-Quran 
    (3/697): This indicates that we have to teach our children and wives 
    religion and goodness, and whatever is essential to good manners. 
This is supported by the 
    words of the Prophet  (peace and blessings of Allah be upon him): “Each 
    of you is a shepherd and each of you is responsible for his flock.” It is 
    well known that just as a shepherd is required to guard and protect those 
    under his care, he is also required to discipline them and teach them. End 
    quote. 
The great scholar Ibn 
    Katheer (may Allah have mercy on him) said, commenting on this verse: 
    Qatadah said: He should enjoin them to obey Allah and forbid them to 
    disobey Allah. He should take care of them as Allah has commanded and 
    enjoin them to obey Him and help them to do so. If you see any disobedience 
    to Allah, you should rebuke them for that. End quote. 
If the brother has done the 
    marriage contract with this woman, then she is his wife and he has to strive 
    to teach her about her religion and help her to learn, but kindness and 
    gentleness should be the method he uses in achieving this aim. The Prophet 
     (peace and blessings of Allah be upon him) said: “When Allah wills 
    good for the members of a household, He introduces kindness to them.” 
    Narrated by Ahmad; classed as saheeh by al-Albani in Silsilah 
    al-Ahadeeth al-Saheehah (3/219). 
He has to stop her doing 
    that which will harm her religious commitment, such as listening to 
    misguided du'at, if what they promote is misguidance and scholars whose 
    religious commitment and knowledge is trustworthy have warned against them. 
    This applies if she is unable to distinguish between truth and falsehood. 
    But if she knows what is true and there is no fear that she may be 
    influenced by what the misguided du'at say, then there is nothing wrong 
    with her listening to them and accepting what is true and ignoring what is 
    false. This applies to the innovations that the scholars have denounced and 
    warned against. As for issues where there are differences of scholarly 
    opinion where ijtihad is allowed and the scholars have different points of 
    view, it does not matter if the ordinary person follows one of them. 
To sum up: You have to 
    protect your wife from misguidance and following whims and desires, but you 
    should be gentle with her, and try to convince her that people do not accept 
    falsehood unless it is mixed with truth so as to confuse them. If she 
    understands this, she will be convinced, in sha Allah. You should also try 
    to provide a suitable alternative from du'at and scholars who are 
    trustworthy with regard to their religious commitment and knowledge, and who 
    attract people by their good presentation skills. You will find many of this 
    type, praise be to Allah. 
May Allah help us and you 
    to do that which He loves and which pleases Him. 
And Allah knows best.
