The differences between Arab and Indian people are many. The majority of Arab people live in the Middle East (Western Asia) and North Africa, while the majority of India people live in India, which is located in South Asia. The languages spoken by each group come from dissimilar, unrelated language families, and their religious traditions and social customs differ significantly.
Most Indian people follow one of the four major world religions that were formed in India: Hinduism, Jainism, Sikhism, and Buddhism. Hinduism, born out of Brahmanism, is believed to be the oldest religion, having formed 5,000 years ago. It has the greatest following with 80% of the population of Indians being adherents and is the 3rd largest world religion, though, Buddhism and Sikhism are 3rd and 5th, respectively. Of the four, Jainism has the least followers; however, over four million people in India and its diaspora are adherents. Other minority religions include Christianity, Judaism, and Islam.
In the Arab world, however, Islam is predominant and many countries have Islam as the official religion. In some nations, Islamic law known as Sharia fully or partially guides the legal system. Islamic traditions and customs permeate the daily lives of many Arab people, from greetings to work hours, social norms, and diet. Certainly, these vastly different religions, Islam and Hinduism, inform the point of views and lifestyles of their devotees, as well as, that of the general populations in the Middle East & Maghreb, and India, respectively, due to their pervasive impact.
The dominant language of India is Hindi, however, India has 22 official languages and more than 200 with a significant (10,000+) number of speakers. Some of the better known languages of India are: Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada and Punjabi. There are several dialects of Hindi, an Indo-Aryan language like many of the languages spoken in India. The Hindi language is written in the Devanagari alphabet.
