if a man and a women commit a zina act together by doing a sexual act for e.g. the girl performing oral sex and the man touching her breast but they both did not have sex with eachother before marriage and afterwards they get their nikkah done they ask Allah forgiveness after they got their nikkah done a couple days later from committing the sin/haraam act before marriage do they have to do their nikkah again? please help as I am in desperate need for an answer and I wanted to know if the marriage is valid or not with eachother.
I would like to know what the prophet s.a.w. said about this in reference and what Allah mentions about it too if you can please with hadith and quran quotations.
