In Islam, belief in One God is the most important belief. Allah in Arabic refers to the One God. It is a known fact that every language has one or more terms that are used in reference to God and sometimes to lesser deities. This is not the case with Allah. Allah is the personal name of the One true God. Nothing else can be called Allah. The term has no plural or gender. This shows its uniqueness when compared with the word ‘god’ which can be made plural, gods, or feminine, goddess. It is interesting to notice that Allah is the personal name of God in Aramaic, the language of Jesus and a sister language of Arabic. The One true God is a reflection of the unique concept that Islam associates with God. To a Muslim, Allah is the Almighty, Creator and Sustainer of the universe, Who is similar to nothing and nothing is comparable to Him. (Monotheism)
In Islam, all humans are created equal. For example, there is no superiority of an Arab over a non-Arab, or vice versa. Blacks and whites have no superiority over each other. The same holds with any other nationality or ethnicity. Islam rejects characterizing God in any human form or depicting Him as favoring certain individuals or nations on the basis of wealth, power or race. He created the human beings as equals. They may distinguish themselves and get His favor through virtue and piety only.
Muslims eat all wholesome and good food including meat of Cow (beef), lamb, goat, and chicken.
Muslims believe that each person has a body and soul. At death, your body is separated from your soul. Your faith and actions in this life will determine your fate in the Life After Death. There is a Day of Judgment when this life will come to an end for every one, and all humans from Adam to the last person, will be brought to a second life, rejoining of your body and soul. On that Day, God will put people in Hell or Heaven based on their beliefs and deeds of this life.
Hinduism has many deities. This is much like ancient Greek and Roman religions. The god Brahma is the creator of the world. The god Vishnu who preserves the world through his many incarnations. The god Shiva will destroy the world which will be rebuilt by Brahma. In their Rig-Veda Book, we find prayers to some 70 objects, each serving as a deity. The concept of god Brahma is similar to the concept of Trinity in Christianity. The Brahma is responsible for all workings of the world and everyone is a part of him. Different gods are viewed as different aspects of him. (polytheism)
Hinduism has a caste system, with four major castes. Members of each are required by strict religious laws to follow certain hereditary occupations and to refrain from intermarriage or eating with members of the other castes. The highest, or priestly and intellectual, caste is that of the Brahmans. The remaining three in order are Kshatriya (ruling or warrior caste), Vaisya (common artisan and agricultural caste), and the Sudras (the low caste people).
Cow is a sacred animal and a deity for Hindus. Cows, therefore, cannot be killed or eaten in Hinduism.
Hinduism believes in body and soul. Your soul returns to your body after your death. This cycle repeats seven times according to some. Your status or caste in next life depends on your deeds of the previous life.
This is called Reincarnation in Hinduism.
