Short answer
Marriage should not be based on coercion, and genuine consent is an important part of marriage.
Islamic Guidance
What Islam teaches
Islam recognizes the importance of consent in marriage and prohibits treating women as possessions. A marriage decision should be made with the free agreement of the people entering the marriage.
Practical Guidance
What you can consider
Parents should guide and advise rather than force. A person who is being pressured should speak to a trusted elder, scholar or appropriate authority before proceeding with a marriage they do not genuinely accept.
