You don't wait 6 months to get married and there is no gigantic engagement party.But that's not to say you can't have an engagement party.
What people here in Britain call dating, Muslims prefer to use 'courting'.
And while a date is usually focused on 1) Sex 2) New encounters and 3) Good times, Islamic courting has different priorities altogether.
Part 2: The big party afterwards is a public announcement known as the Walima, catered and sponsored by the husband. It's not supposed to be costly but it is supposed to be joyous and open to all.
The Islamic Golden Age is traditionally dated from the mid-7th century to the mid-13th century at which Muslim rulers established one of the largest empires in history.
Remember the ultimate Muslim belief: there is One True God Who creates love and unites people.
