The largest country through which the equator passes is Brazil. The equator crosses northern Brazil near the city of Macapá.
The equator crosses parts of Africa, Asia, and South America.
The Prime Meridian crosses, among others, the countries of Algeria, Mali, and Burkina Faso. I'm sure the answer to the question is among those, but I'm not sure which of those is considered an 'Arab' country.
The places where the ecliptic crosses the equator are called the vernal equinox (where the Sun crosses from south to north) and the autumnal equinox (where the Sun crosses from north to south). These are the points where day and night are equal in length, marking the beginning of spring and autumn, respectively.
Ecuador is the South American country that is crossed by the equator. The country's name comes from its location on the equator, and its capital city, Quito, has a famous monument marking the exact location of the equator.
