He gave his wife gold and they had an argument; does he have the right to ask for it back?
Question

                I am a married man, and there was an argument between me and my wife. Now I want her to give back the gold I gave to her at the time of marriage, so that I will give her the rest of the things that belonged to her that I have with me.

Is it Islamically permissible for me to ask to be given back things that I gave her apart from the mahr?.
Praise be to Allah.
    If a man gives his 
    wife gold that is not part of the mahr, if his intention was to give it as a 
    gift, then the gold has become her property, and it is not permissible for 
    him to take back this gift. 

    Al-Bukhaari (2589) 
    and Muslim (1622) narrated that Ibn ‘Abbaas (may Allah be pleased with him) 
    said: The Prophet (sa) said: “The one who takes back his gift is like the 
    dog which vomits then goes back to its vomit.” 

    Al-Bukhaari (2622) 
    also narrated: “We are not like the bad example of the one who takes back 
    his gift; he is like a dog that goes back to its vomit.” 

    This hadeeth 
    indicates that it is haraam to take back a gift. 

    The scholars of 
    the Standing Committee for Issuing Fatwas were asked: A man gave his entire 
    house and all the furniture in it as a gift to his wife;  can he take back 
    his gift, and how? 

    They replied:

    If the wife has 
    not taken possession of what her husband gave her in a way that is 
    customarily regarded as taking possession of something, then he may take 
    back his gift. Hoever, this is not regarded as dignified conduct, because 
    the Prophet (blessings and peace of Allah be upon him) said: “The one who 
    takes back his gift is like the dog that goes back to its vomit.” If she has 
    taken possession of it in a manner that may be regarded as attaining 
    ownership according to custom, then it has become her property and he cannot 
    take it back, according to Islam, except with her consent. Nevertheless, if 
    he takes it back after she willingly returned it to him, that is contrary to 
    decency and dignified conduct. If they disagree concerning the gift and what 
    is regarded as taking possession of it, then the matter should be settled in 
    the sharee‘ah courts.

    Fataawa al-Lajnah ad-Daa’imah, 16/247 

    Shaykh ‘Abd 
    al-‘Azeez ibn Baaz, Shaykh ‘Abd ar-Razzaaq ‘Afeefi, Shaykh ‘Abdullah ibn 
    Munay ‘ 

    But if he gave her 
    the gold as a loan, to use it and wear it as an adornment, and it is still 
    his property, then this gold belongs to the husband, and is not the wife’s 
    property, so he may ask her to return it to him. 

    And Allah knows best.
