i searched through all the relevent sections but i could not find the answer for my question.so i am asking it here. i was engaged to my present wife. and during the engagement period (before Nikah) we used to meet and touch and kiss and fondle with each other.. etc . but we never committed an intercourse. and later on we married. now i came accross the ayat of sura Noor for which some scholars say that a couple who had committed Zinna with each other, then they can not marry each other. another related question is that in some parts of pakistan people use to renew their marraige contract (Nikah) without any sharee requirement. Is it permissible to renew ones Nikah if the earlier nikah is still valid.
