She became Muslim recently, and she appointed a Muslim man as her guardian, and he married her himself
Question

                There is a woman who became Muslim in one of the Latin American countries, then she came to Egypt to learn Arabic and Islam, and she made me her guardian in Egypt. Then we agreed to get married, so I married her to myself in the presence of witnesses of good character. They asked her if she accepted me as a husband, and she replied that she did, and the marriage contract was done, and we announced our marriage to our circle of acquaintances.

My question is: is it permissible for the guardian to marry the woman under his guardianship to himself, with her permission?

Please note that she has no guardian at all among her relatives, because she is the only Muslim in her family. I hope that you will quote evidence for it being permissible or otherwise.
Praise be to Allah.
	In order for marriage to be valid, it is stipulated that the 
	marriage contract be done by the woman’s guardian or his deputy, because the 
	Prophet (blessings and peace of Allah be upon him) said: “There is no 
	marriage except with a guardian.” Narrated by Abu Dawood (2085), at-Tirmidhi 
	(1101) and Ibn Maajah (1881), from the hadith of Abu Moosaa al-Ash‘ari; 
	classed as saheeh by al-Albaani in Saheeh at-Tirmidhi.

	And the Prophet (blessings and peace of Allah be upon him) 
	said: “Any woman who gets married without the permission of her guardian, 
	her marriage is invalid, her marriage is invalid, her marriage is invalid… 
	And if they differ, then the ruler is the guardian of the one who has no 
	guardian.” Narrated by Ahmad (24417), Abu Daawood (2083) and at-Tirmidhi 
	(1102); classed as saheeh by al-Albaani in Saheeh al-Jaami‘ (no. 
	2709).

	If this woman does not have a Muslim guardian among her own 
	male relatives (on the father’s side), then the Muslim judge should do the 
	marriage contract for her, because the Prophet (blessings and peace of Allah 
	be upon him) said in the hadith: “And if they differ, then the ruler is the 
	guardian of the one who has no guardian.”

	Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) 
	said: As for the woman who has no guardian, then if in the town or locality 
	there is a representative of the ruler, he may do the marriage contract for 
	her, or that may be done by the emir (chief) of the Bedouin, or the head of 
	the village. If there is among them a leader who is in a position of 
	authority, then he may also do the marriage contract for her, with her 
	permission.

	End quote from Majmoo‘ al-Fataawa (32/35)

	Islam has given the guardian authority over marriage because 
	of his compassion for the woman and his concern for her best interests. This 
	is apparent in the case of the father, grandfather, brother and other male 
	relatives of the woman who are concerned about her best interests. If she 
	has no such relatives, then the ruler and the judge who take care of the 
	interests of the Muslims, so guardianship is given to them, and not to 
	individuals who may not care about the woman’s interests or who may give 
	their own interests precedence over hers, especially if an individual takes 
	over her guardianship so that he may marry her to himself.

	Based on that, you erred by taking on the guardianship of 
	this woman, because there are Muslim judges in your country; therefore you 
	have to repeat the marriage contract. 

	If the judges in your country follow the view of those 
	scholars who say that it is valid for a woman to do her own marriage 
	contract, then in order to be on the safe side, for yourself and for her, 
	you should appoint a Muslim man as her guardian, then he can give her to you 
	in marriage.

	Secondly:

	The woman’s guardian can marry her, if she consents to that.

	See the answer to question no. 104662 
	for more information on the format of the marriage contract in that case.

	And Allah knows best.
