What is the most popular last name in Saudi Arabia?

Answer 1

There are many,

Al Harbi, Al Otaibi, Al Kahtani, Al Zahrani, Al Ghamdi, Al Dossari and more..

These last names are not in a rank but Al Harbia may be the most popular. They are spread from the center of Saudi Arabia till the southern. All these Families are Muslims and witnesses that there is no god but Allah and Muhammed is his Messenger (pbuh)..

So, they are equal..

that's right the last names u said very popilar , but , it's a tribes name not a last names , not every body use them , & you forgot to say "tamim " the biggest Arabian tribe

may god bless you all
