Religion is the belief in and worship of a superhuman controlling power, especially a personal God or gods.
An Abrahamic religion is a religion whose followers believe in the prophet Abraham and his descendants to hold an important role in human spiritual development. The best known Abrahamic religions are Judaism, Christianity and Islam. The abrahamic religion spread globally through Christianity and then to Islam in the 7th century, and the major Abrahamic religions in chronological order of founding are Judaism. At this point of time, Christianity, Islam and Judaism are the religions with greatest numbers of adherents, especially Christianity with 2.3 billion people that practice it. Although, statistics claim that Islam will be the top religion in the future. Even though members of Judaism, Christianity, and Islam do not all claim Abraham as an ancestor, some members of these religions have tried to claim him as exclusively theirs. The Abrahamic God is conceived of as eternal, omnipotent, omniscient and as the creator of the universe. God is further held to have the properties of holiness, justice, omnibenevolence and omnipresence. Proponents of Abrahamic faiths believe that God is also transcendent, but at the same time personal and involved, listening to prayer and reacting to the actions of his creatures, this god has multiple names in each of these religions, for example in Islam it is Allah and in Judaism, it is in the Tetragrammaton~YHWH, in Christianity, it is Jesus.
These religions have a lot of differences, not only in their context and their meaning but also with the people who practice each religion. Which means, every single one of them believe that their book is the word of God. But, Islam does believe that the Original versions of the Turah and the Bible are the words of god, but they were modified to deceive people and the Quran is the primary book of all humans, and the Prophet Muhammed is the only last messenger that we should follow his instructions given to him from Allah.
Historically, the Abrahamic religions have been considered to be Judaism, Christianity and Islam. Some of this is due to the age and larger size of these three. The other, similar religions were seen as either too new to judge as being truly in the same class, or too small to be of significance to the category. However, some of the restriction of Abrahamic to these three is due only to tradition in historical classification. Therefore, restricting the category to these three religions has come under criticism.
