Is this true that if a woman forgives the meher of her husband, then she will go to heaven?

Actually, in my country (india) it is us women who pay dowry to men. Dowry includes money, furniture, kitchen appliances, curtains, bedsheets, car, ac, refrigerator and even sometimes a house. Every small thing is given by girl’s father to boy’s family that is required in the house.

In most of the cases, the islamic meher is never paid to women. It is also forgiven. The groom asks the girl to forgive the meher, and she has to forgive. If she will not forgive then issues and fights happen.

Generally, in majalis also it is said to forgive the meher. Is this true? Should women forgive the meher? But if we are to forgive the meher then why was it created in the first place?
