There is a limit in the relation between the man and woman in their engagement period (I don't want to go so far with this J) So there is another step and this is (tying the nut) this is the exact translation to the Iraqis language where the couple become legally married in court but they still don’t get to live together.
In this contract the man usually writes her some kind of money or gold which she will take if he divorce her or he dies.
This is usually done in court and some families bring the judge to the house of the bride where more traditional ceremonies can take place. (Don't ask me why because I don't know) but I think it’s traditions only and the people like to make it.
For Sunnis the bride wear a white dress or Jallabyia, a tradition Arabic cloth, and in front of her they put seven cups, containing different kinds of white things like sugar, yoghurt, cream, (I don't remember the others! Usually the judge asks the bride personally if she agrees to marry this man by saying a long traditional speech and he repeats it for three times (I don't know why) and then the bride says Yes.
Most of our marriages are arranged in the traditional way (i.e., not after a love story).
When a man sees a woman and he likes her form the first sight he tells his mother about her and his family starts to ask about her family and start to work like a detective and if they match with the groom family socially and economically and in other things they agree about her.
The guests starts to dance and celebrate the new marriage.Of course these traditions may differ a little bit according to the social and economical levels and according to beliefs as well but this is the basic thing.Some of the families started to shrink those parties into two or three depending on the security and economical conditions as well. The traditions I'm talking about are in the cities not villages.The first thing to do after the initial agreement is called ‘Mashaiya’ in which the groom's family bring the older person in their family with a number of relatives and friends all just men and go to the Bride father who also brings all his relatives and friends all men and sit together to get introduced to each other and in this party the older person in the groom's side make a speech asking for the bride’s hand from her father, the father makes another speech saying yes, then juice and deserts are serviced at once and after they finish, everybody leaves home.The sab’a as we call it comes after the marriage in seven days (now some of them makes it after ten or 14 days according to their honey moon but it is supposed to be made in the seventh day after marriage).
