Non-Muslim Proposing to Muslim Woman

Dear Brothers & Sisters,
As-Salaamu-Alaikum wa Rahmatullahi wa Barakatuh. (May Allah's Peace, Mercy and Blessings be upon all of you)
One of our brothers/sisters has asked this question:
Assalam O Alaikum

I am a muslim. My sister has been proposed to by a man who is christian. She has agreed and they are now planning to get married. The man is willing to convert to Islam. I dont know what to do. Do I have any rights to resist this marriage? My parents are totally against this marriage and are deeply concerned, mainly due to the fact that the man is from a different culture and is not a relative.

Please advise me on what to do as I am very confused and time is running out very fast. I will await your reply anxiously.
Thankyou.

The marriage contract is not valid if the man’s sister asks for the hand of the woman for her brother, in the presence of the woman’s guardian

Answer:

Praise be to Allaah.

It is not permissible for your sister to marry this man unless two conditions are fulfilled:

  1. He must enter Islam.

  2. Your father must agree because he is her guardian who is responsible for arranging her marriage.

If either of these conditions are not fulfilled, then try to stop this evil from happening, whatever it takes.

And Allaah is the source of strength.

Whatever written of Truth and benefit is only due to Allah's Assistance and Guidance, and whatever of error is of me. Allah Alone Knows Best and He is the Only Source of Strength.
Your brother and well wisher in Islam
