Marrying a girl who committed zina

Q: I want to know a fatwa on zina. If a girl do zina once in her life before engagement with someone else and seeks forgiveness from Allah and after sometime she got engaged with a person who did not do zina in his entire life and the girl tells her fiance that she did zina mistakenly. Now she seeks forgiveness since she did this sin. What is the order of shariah about this? Is the nikah halal or haram with that girl?

Being forced to attend a khatam

Q: My family has a katham every year, the changing of the flags. I know it's not as per the Prophet (sallallahu alaihi wasallam) teachings, and it's innovation. But I'm forced to do it, as I will get shouted at.

Please advise, am I sinning if I do the katham? I tried to refuse previously and I got swearing. They don't understand it's not as per the sunnah and I'm living under their roof. So I'm basically forced to do it. What do I do?
