Yemen (Arabic: اليَمَن al-Yaman) is an Arab country in Western Asia, occupying the southwestern to southern end of the Arabian Peninsula.
It is bordered by Saudi Arabia to the north, the Red Sea to the west, the Gulf of Aden and Arabian Sea to the south, and Oman to the east.
One etymology derives Yemen from yamin, meaning "on the right side", as the south is on the right when facing the sunrise. Another derives Yemen from yumn, meaning "felicity", as much of the country is fertile. The Romans called it Arabia Felix (Happy Arabia) as opposed to Arabia Deserta (Deserted Arabia). Yemen was mentioned in Old South Arabian inscriptions as Yamnat. In Arabic literature, the term Al-Yaman includes much greater territory than that of the republic of Yemen; it stretches from northern Asir to Dhofar.
The studies of Quzi Athar Mubarakpuri also bring to light that the Jats did not remain confined to Persia. They got settlement in different Parts of Arab land, which was under the Persian rule in those days. The Arab geographers testified that fact that in the coastal region of the Persian Gulf from Ubullah to Bahrain they had many pockets of their population and that they engaged themselves in different kind of work including cattle breeding. ,  It is also confirmed by the Arab historians that in pre Islamic period their largest concentration was found in Ubullah, a fertile and pleasant place near the city of Basrah. Their second big settlement was in Bahrain where they had been residing in large numbers prior to the period of the prophet (SAW) as we are informed by Al-Baladhuri and other historians  In the same way, there are clear evidences for their settlement in Yemen before the advent of Islam and their important role in socio- political life of those days Yemen. In the times of pious Caliphs when Persia and many parts of the Arab region (previously ruled by Persian and Roman Kings) came under the Muslim army and a number of them got converted to Islam also. It is confirmed by different historical and geographical works, as cited by Maulana Mubarakpuri that they had settled in large number in Antioc and coastal town of Syria under the patronage of the pious and Umayyad caliphate (Khilafat-e-Rashidah and Banu Umayyab) , 
It is very interesting that we come to know through the studies of Maulana Mubarakpuri that the Jats residing in Bahrain, Yemen and other coastal regions in a large number had influenced the local Arabs by their language to such extent that the latter lost the originality and eloquence of their language. For the same reason the language of the people of the tribes of Banu Abd Qais and Azd was declared to be diluted and unauthentic due to their mingling and frequent interaction with Persian and Indian people. ,
