Refusing a non-committed suitor despite the mother's pressure

Question:
This questioner says: My maternal cousin’s son proposed to me. He is a man who is not committed to his religion, and Allah has blessed me with commitment. So I refused him for this reason. My mother is keen on him and tries to pressure me to agree to him, to the point where she cries day and night. She tells me she is angry with me because I did not agree to him. What is the ruling on my action? And is it considered undutifulness to her? Knowing that my father has passed away, and my guardian is my brother, who has not yet married. My mother considers him too young in this matter, and he is unable to offer his opinion in this affair.

Answer:
Marriage is your right. You do not marry except one whose religion and character you are pleased with. Your mother has no right to force you to do what you do not want. If you differ with her in this, you are in the right and have taken your right, and she is the one who is in the wrong. She is the one who is in the wrong. Yes.

The presenter:
May Allah reward you.
