He agrees with the opinion of Ibn Hazm about intimacy. Is it permissible for his wife to engage in foreplay with him when he is fasting?
Question

                If a husband follows the opinion of the Zaahiris (literalists), Ibn Hazm and al-Albaani, which says that emission of semen when fasting without having intercourse does not invalidate the fast, is it permissible for his wife to engage in foreplay with her husband during the day in Ramadaan, even if that results in emission of madhiy (prostatic fluid) or maniy (semen) from him?.
Praise be to Allah.Firstly: 
The ruling 
    on emission of madhiy is different from the ruling on emission of maniy. The 
    most correct scholarly view is that emission of madhiy does not invalidate 
    the fast, whether it is from a man or a woman. The scholars' opinions on 
    this issue have been mentioned in the answer to question no.
    49752. 
Secondly: 
It should be 
    noted that it is not permissible for anyone to adopt the opinion of any 
    scholar on the basis of convenience, or because this opinion suits his whims 
    and desires. When there is a difference of scholarly opinion, what we must 
    do is that which Allaah has enjoined in the verse where He says 
    (interpretation of the meaning): 
“(And) if 
    you differ in anything amongst yourselves, refer it to Allaah and His 
    Messenger, if you believe in Allaah and in the Last Day. That is better and 
    more suitable for final determination”
[al-Nisa’ 
    4:59]
It is not 
    permissible for anyone to say: I will follow the opinion of such and such a 
    scholar, and thus go against a hadeeth which is proven from the Prophet  
    (peace and blessings of Allaah be upon him). 
Hence Imam 
    al-Shaafa’i (may Allaah have mercy on him) said: The scholars are 
    unanimously agreed that if a Sunnah of the Prophet  (peace and blessings 
    of Allaah be upon him) is proven, it is not permissible to forsake it for 
    the opinion of anyone. End quote. Madaarij al-Saalikeen (2/335). 
Once the 
    ruling is proven with saheeh evidence, no one’s opinion counts, no matter 
    who he is. 
The view 
    that masturbation or intimacy with one's wife to the point of ejaculation 
    are among the things that invalidate the fast is the view of the majority of 
    scholars, including the four imams, Abu Haneefah, Maalik, al-Shaafa’i and 
    Ahmad. They quoted as evidence the fact that it is satisfaction of desire, 
    and that is forbidden to the person who is fasting, because Allaah says, 
    according to the hadeeth qudsi about the fasting person: “He gives up his 
    food, his drink and his desire for My sake.” Narrated by al-Bukhaari 
    (1894). 
This has 
    been explained in detail in the answer to questions no.
    71213and 65698. 
We do not 
    deny that there is a difference of opinion on this issue. Ibn Hazm and 
    Shaykh al-Albaani (may Allaah have mercy on them) both thought that emission 
    of semen as the result of intimacy with one's wife does not invalidate the 
    fast. If someone adopts this opinion on the basis of knowledge and follows 
    it on the basis of evidence, not on the basis of his whims and desires, then 
    there is no sin on him for that, because a person is only responsible within 
    the framework of his knowledge, but that is subject to the condition that he 
    only believes that on the basis of what evidence and scholarly opinions he 
    has available to him, and is not simply looking for a concession and the 
    easiest opinion. 
It is not 
    permissible for a Muslim to follow the mistakes of the scholars; if he does 
    that, all evil will be combined in him. Hence the scholars said: Whoever 
    follows a matter concerning which the scholars differed and follows the 
    easiest opinion is a heretic, or almost a heretic. End quote. See also the 
    answer to question no. 22652. 
What we 
    advise the questioner to do is to be content with that which the scholars 
    have agreed is permissible, which is intimacy in the form of touching or 
    kissing, without ejaculating, so as to protect his fast and fulfil his duty, 
    and for fear of falling into that which is haraam and invalidates the fast 
    according to consensus, namely intercourse. 
 And Allaah 
    knows best.
