Answer the question at the end by quoting:

Arabic weddings (Arabic: zff, frH, or 'rs) have changed greatly in the past 100 years. Original traditional Arabic weddings are supposed to be very similar to modern-day Bedouin weddings and rural weddings, and they are in some cases unique from one region to another, even within the same country. it must be mentioned that what some people today call "Bedouin" wedding is in fact the original true traditional Arab Islamic wedding without foreign influence. The marriage process usually starts with meetings between the couple's families, and ends with the wedding's consummation (leilat al-dokhla).
Arranged marriages still happen in the Arab world. The traditions of conservative Arab society and Islam forbid couples to have sex or socialize before marriage (however forced marriages are against Islamic teachings). Therefore, when it is time for a young man to get married, his family will look around to identify a number of potential brides. Arranged marriage is a tradition of Arab nations of West Asia and North Africa, but with the difference that between 17% to majority of all marriages in these countries are also consanguineous marriages. In Saudi Arabia, majority (65%+) of all marriages are endogamous and consanguineous arranged marriages. More than 40% of all marriages are endogamous and consanguineous in Iraq, Jordan, Syria, Yemen, Kuwait, UAE, Oman, Sudan, Libya and Mauritania; and over 1 in 5 marriages in Egypt and Algeria. Among these Arab people, arranged marriages include endogamous and non-consanguineous marriages, and therefore exceed the above observed rates of endogamous and consanguineous marriages. Arab Christians such as Coptic Christians in Egypt. Marriage was a central feature of traditional Aboriginal societies. Freedom of marriage was restricted to ensure children were produced according to the correct family groups and affiliations and avoid marriages with certain close relatives or marriages with any one outside the group. Nevertheless, opinions vary on whether the phenomenon should be seen as exclusively based on Islamic practices as a 1992 study among Arabs in Jordan did not show significant differences between Christian Arabs or Muslim Arabs when comparing the occurrence of consanguinity. Traditionally, the process of investigation takes into consideration the girls' physical beauty, her behavior, her cleanliness, her education and finally her qualities as a housewife. In carrying out this traditional investigation parents also take the behaviour of the prospective bride's family into account. The first meeting usually takes place between the bride, groom, and their respective mothers. They meet, usually in a public place or in the bride's house, and get to know each other. The bride, groom, and their chaperones will typically sit separately, but within sight of each other, in order to get to know each other. Nowadays, the man might suggest to his family who he would like them to consider, and it may be that the man and the woman already know each other. It is also nowadays common in urban families for a bride and the groom to agree to marry before the groom approaches the bride's family for their permission.
