Yes offer salat istekhara as the sister says
Bear in mind that The act of forced marriages is something that is not good, nor fruitful whether it is man being forced or woman being forced into marriage , because its foundation is corrupt, and whatever stands upon a corrupt foundation shall eventually falter and will not have a good ending.
Aa'ishah reported that a girl came to her and said, "My father married me to his brother's son in order to raise his social standing, and I did not want this marriage [I was forced into it]." ?Aa'ishah said, "Sit here until the Prophet
(peace and blessings of Allaah be upon him) comes. The Messenger of Allaah
(peace and blessings of Allaah be upon him) came and she told him about the girl. The Prophet
(peace and blessings of Allaah be upon him) sent for her father
, then he gave the girl the choice of what to do. She said, "O Messenger of Allaah, I have accepted what my father did, but I wanted to prove something to other women." (Reported by al-Nisaa'i, 3217).
So as you can see, a lady came to Aisha informing her that her father had forced her to marry someone she did not want, Aisha called the prophet Muhammad to see what his ruling on the matter would be, and as you can see the prophet then sent for her father, and gave the girl a choice in the matter, as to whether she wanted the marriage to remain intact or get a divorce.
Hence this makes it all clear that forced marriage is not allowed, . Another hadith records the prophet Muhammad saying:
So whenever the prophet Muhammad makes a ruling on a matter, we must follow it, and we have no right to contradict it, to do so is to commit a major sin, hence any Muslim who thinks its okay to force a person into marriage is committing a major sin since they are disobeying God because he called on us to obey the prophet.
So therefore forced marriage is not allowed, it is corrupt, and a corrupt foundation does not have a fruitful ending. Last but not least, here is what Allah says concerning this matter:
004.019
YUSUFALI: O ye who believe!
Ye are forbidden to inherit women against their will. Nor should ye treat them with harshness, that ye may Take away part of the dower ye have given them,-except where they have been guilty of open lewdness; on the contrary live with them on a footing of kindness and equity. If ye take a dislike to them it may be that ye dislike a thing, and Allah brings about through it a great deal of good.
Allah the most high forbids the act of forced marriage, so therefore this act is a sin and against God's true teachings
