I possess a little problem regarding my Nikaah. I understand It's somewhat individual, but I'm eager for a solution. I've experienced a wedding (Nikaah only) into a girl residing in a different country (long-distance connection) for 2 years now. I've visited visit her often within both of these years, but I've not rested with her. My problem is simple; is my Nikaah invalid? Since I've seen from the few people who if your pair don't have any sexual relations for 3 months, then your Nikaah is instantly annulled. Is this correct? If that's the case, may anybody present me with data from Quran or Hadeeth?
