Prophet Abraham (pbuh) had two wives Sarah and Hagr. Ishmael was born from Hagr, and he was the first-born of Abraham (pbuh). On the other hand, Sarah gave birth to Isaac and he was the second son of Abraham (pbuh). Prophet Jacob was the son of Prophet Isaac. Jacob and his family was chosen by Allah to shoulder the responsibility of preaching Allah's guidance to mankind, and Allah, the Almighty gave him the title'Israel', which means 'SOLDIER OF ALLAH' or ' THE CHAMPION OF ALLAH' , and his descendents are known as Bani-Israel or the children of Israel.

However, later after the death of Joseph, new kings or pharaos started ruling Egypt. The King Ramses II, is believed to be the Pharao during the time of prophet Moses. The condition of the Bani-Israelis then were very miserable. They were kept in slavery and were forced to do very hard and odd jobs. The then kings or 'pharao's were afraid of the coming of a prophet from among the Bani-Israelis, which they came to learn from their fortune tellers. This is why, the Egyptian kings were very cruel to them, and at one point all new-born male children were ordered to be killed by the pharao. However, Moses (pbuh) eventually proved to be that Prophet, and he called the then pharao to follow the commandmends of Allah.

It should be mentioned here that the old Egyptian belief was that human beings were born of a cow. As the cow gives milk to her calf with love and affection, and human beings are like calves, they used to worship cows as mothers. They were also engaged in worshiping idols, fire, wind and other forces of nature. The Bani-Israelis were also engaged in all these sort of activities as they forgot the one True God long ago.

We (the Jews, Christians and Muslims) are all familiar with the story of the Ten Commandments very well.The Pharao of the time of Moses (pbuh) did not accept the one true God to be the Supreme, instead he became furious to Moses. Later, Moses was commanded by Allah to free the Bani-Israelis from the captivity and take them out of Egypt. Allah's intention was to take the Bani-Israelis back to the holy land of Palestine. We also know that although Pharao let the Bani-Israelies go with Moses in the first instance, later he decided to kill them and he and his soldiers chased them upto the river Nile. We also know how Allah, the one true God saved Moses and his people, and how pharao and his soldiers were drowned in the river.

Both Moses and Aaron were with the Bani-Israelis when they eventually reached Mount Senai. Allah's favour was with them, and Allah was sending food to them from the heavens. However, when Allah commanded them through Moses to fight with the Roman soldiers (who were the then occupying force in Palestine) and promised Allah's help in regaining Palestine, the ignorant people disagreed and simply laughed at Moses. As a result, prophet Moses got angry and the Bani-Israelis were deprived of Allah's favour.

It is said that prophet Moses died in the mount Senai valley after 40 years. The followers of prophet Aaron went to a new place, which was later known as Iran (the abode or living place of Aryans). Also, some of the Bani-Israelis were able to occupy the holy land Palestine later. Now, the ignorant Bani-Israelis were following the Egyptian culture and tradition, although Moses and Aaron  tried their best to forbid them to worship different deities during their life time. And after the death of Aaron, those people might have forgot or mixed up the old Egyptian traditions with the teachings of one True God (Allah). Thus, the religion of Iran or old Persia was to worship idols, fire etc., although some beleievd that there was one God. The name of the religion became known as Persi religion.

The Persi religion was thus prevailing in Iran, and at one point in time a king, called Gustashop was ruling Persia or Iran. Gustashop was a good, kind-hearted and knowlegeble king. He had a good number of wise counsellors in his court. During his rule, a person in Persia, called Zoroa-Star started preaching a new doctrine. He was telling people that human beings should worship one true God and that they should not worship fire or idol etc. However, the general people got angry and Zoroa-Star was finally brought to the court of king Gustashop. Gustashop arranged for a debate between Zoroa-Star and the wise counsellors. After a lot of arguments, Zoroa-Star came out victorious and from that day king Gustashop ordered everybody to follow the teachings of Zoroa-Star, which was a pure Monoethism or worshiping one True God.

However, some people opposed his view and were adament to follow the old tradions of their forefathers. As a result, a civil war broke out and eventually the old tradional people were driven out of Iran. These Aryan people later crossed the Pamir Valley in search for a land to live, and they finally came to a place known as Hindustan, which was the living place of the descendents of Hind (who was the grand son of Prophet Nuh (pbuh) or Noah). This information has been collected from the book "Al Milal Wan Nihal" by Imam Ibn Hazam and Shahrastani. Now, let us draw a brief outline about Hindustan or the land of Hind or Ind or India.

As the dispersed Aryans from Iran were very desparate to have a land for their own, they targated Hindustan for their ultimate living place. Slowly they proceeded and tried to achieve political victory in Hindustan. Later, they also tried to achieve religious and cultural victory over the Dravidians. As a result, they had to engange in a lot of battles with the Dravidians. In Rig Veda of the Aryans, the Dravidians have been termed as Slavesand Dacoits. According to the description of the Rig Veda, the Aryans were engaed in war with the Dravidians for a long time.

However, later the Aryans were able to gather enought strength and established their supremacy over the entire Northern Hindustan. Thus, the 'Sindhu' civilization developed by the Dravidians were destroyed. The Dravidians of the Bengal, although kept opposing the invading Aryans, were being indirectly influenced by them. The infulence started since the 'Maurya' victory in 300 B.C., and during the 4th and 5th century (320-500 A.D.), the Aryan religion, language and culture deepened its rute in Hindustan. This Aryan religion later took the name as 'Hindu' religion, and as has been mentioned earlier, the Aryan or old Persi reliogion in Iran took a new shape and became known as 'Zoroa-Starian' religion..

The Puranas of the Aryans have mentioned the Dravidian dynasty as 'Sudra', which is the lower cast of the Aryans. The Aryans had a 'cast system' in their society, and they had 4 casts: Brahmin (for Religious leadership), Khatriya (to fight in war), Baiswa (to conduct business) and 'Sudra' (to do the lower level work like the farmers, labourers, Coblers, Potters, Blacksmiths etc.). It has been understood that the Dravidians after their defeat, were accumulated in the Aryan lower cast.
