I am being forced to marry someone who is marrying me for wrong reasons and according to our traditions and understandings refusal of nikkah is very difficult. What is the advisable Islamic way to refuse?
Explain to your parents that a nikah is valid from Islamic point of view under the following conditions:
1- Supervision and testimony
2- Consensual agreement to marry: No girl/boy or woman/man can be wed against her/his will.
3- Announcement: Marriages, especially the ceremony of nikah is performed in order to announce the marriage. Therefore, nikah must be announced to everybody.
4- Mehr : Legal Share of Bride is given to the bride by the groom. It is not a condition for the nikah to be valid, but the right of mehr arises as a natural result of the nikah for the bride.
Without these it becomes void.
