She wants to get married but her sons refuse
Question

                I have a question that has to do with my mother, who is asking us as her sons to approve of her marriage to a man whom we do not know and who is a stranger to us. Please note that my father died seven years ago and, moreover, she is sixty-three years old. She went with this person to the registrar to record their marriage without our knowledge, but the shaykh refused and stipulated that one of her sons should be present. When we refused to do that, she said that she would never forgive us for not accepting. I hope that you can advise us of a solution to this problem.
Praise be to Allah.
	Firstly: 

	If the husband 
	has died and the woman wants to marry someone who is religiously committed 
	and of good character, the guardian is obliged to arrange that marriage, 
	whether the guardian is her father or her son, if the father is not there. 
	And it is not permissible for anyone to prevent her, because this is one of 
	her rights. It makes no difference whether the woman is old or young, or 
	whether she has children or not. 

	The fact that 
	the woman is old is not a barrier to her getting married, because there are 
	many benefits in marriage, such as the woman’s need for someone to look 
	after her affairs, take care of her, and keep her company in her house, 
	instead of her living alone in her house with no company. 

	What you have 
	to do is ask about this man who has proposed to your mother; if he is good 
	in terms of religious commitment and character, then you have to arrange the 
	marriage and it is not permissible for you to refuse to do so. 

	And Allah knows best.
