Reciting Al-Fatihah at the time of the marriage contract or engagement has nothing to do with the Sunnah; rather it is an innovation (Bid`ah).

If a divorce is issued to the wife before the consummation of the marriage and without having been completely alone together in such a manner that consummating the marriage would have been possible, then she does not have to observe `Iddah, and she is entitled to half of the Mahr that was agreed upon. If a divorce is issued to the wife before consummating the marriage but they have been completely alone together in such a manner that consummating the marriage was possible, then the majority of Hanafi, Maliki, Shafi`i and Hanbali scholars are of the view that she must observe `Iddah and she is entitled to the Mahr in full.
