Man enjoying intimacy with his wife via the internet
Question

                I am married but my wife is currently in another country. Is there any sin on me if I sit with her via the internet and ask her to show me some part of her body and so on? What is the ruling?.
Praise be to Allah.
    We put a similar question to Shaykh Muhammad ibn Saalih 
    al-‘Uthaymeen (may Allaah have mercy on him): Is it permissible for the 
    spouses to speak about sex on the phone and provoke one another until one or 
    both of them reaches climax (without using the hand, as that is haraam)? 
    This is because the husband is always travelling or they only see each other 
    every four months. 

    He replied:

    There is nothing wrong with it; yes, it is permissible. 

    Question: Even if that is using the hand? 

    Answer: Using the hand is subject to further discussion. It 
    is only permissible if the person fears that he may fall into zina. 

    Question: Without using the hand there is objection to it? 

    Answer: Yes, without using the hand there is no objection to 
    it, and if he imagines that he is with her, there is nothing wrong with 
    that. End quote. 

    But the danger with that is that others may spy on these 
    meetings via the internet. 

    This action also promotes doing haraam things such as 
    masturbation etc. So in order to be on the safe side it is better not to do 
    that, because the Prophet  (peace and blessings of Allaah be upon him) 
    said: “Sins are the private pasture of Allaah. Whoever lets his flock graze 
    around this pasture will soon transgress into it.” Narrated by al-Bukhaari 
    (1946). 

    And Allaah knows best.
