And WHY shouldn't he break off the engagement ? Lots of possibilities here:
1.The guy has been doing hanky panky himself in which case he deserves her.
The guy is clean and who knows what else the girl has been doing besides the making out ? She may have been around the block for all we know. In this case, why would anyone wanna ruin the guy's life ?
The guy is great and the girl is great and has truly repented. But then who will be the judge of the sincerety of her repentment.
So yes, IT IS A BIG DEAL !!
Jorey asmaanon pe bante hein. How can you be the one to say whether he deserves her or not? Even if he has done hanky panky. Couples are supposed to compliment one another and make up for the other's deficiencies. Hosakta hai ke Allah mian paired them up because he is more religious then her and he can bring he closer to Allah swt.
These days cleanliness is a very fluid concept to people, men and women. What and who is considered clean is becoming harder and harder to define. You may be right, she may have been around the block a thousand times. But thats none of our business because she isnt working that block anymore. We need to get over it. By marrying someone who has been in a relationship, he is ruining his life? What is your stance on divorcees and widows then? They too are "unclean" people and unworthy of your paak and saaf attention?
Who will be the judge? I dont mean to sound all preachy here but we are after all mere human beings who sin everyday, all day. We dont hold the right to judge someone's sincerity or repentance TO ALLAH SWT. We dont have Confessionals in our religion because the relationship between God and Human has no one in the middle. There is no one else to judge aside from Him. What do sincere people look like and how do you differentiate? Do sincere people carry around halos and insincere people grow horns on their head?
She isnt cheating, uska ghar mat toro. Let two people get married and have a life.
