Monotheistic religion: Islam accepts and worships only one god. “Allah”, being the standard Arabic translation for the word “god”, became how the Islamic god is known as throughout the world.
Abrahamic religion: any religion that can be traced back to Abraham. This includes Christianity and Judaism, referred in the Qur'an as the “people of the book”. Muslims respect these religions because they believe that they all worship the same god, and that the different religious leaders are all prophets to this same god.
The same religion has He established for you as that which He enjoined on Noah - the which We have sent by inspiration to thee - and that which We enjoined on Abraham, Moses, and Jesus: Namely, that ye should remain steadfast in religion, and make no divisions therein: to those who worship other things than Allah, hard is the (way) to which thou callest them. Allah chooses to Himself those whom He pleases, and guides to Himself those who turn to Him.Although Islam is a very rich religion in terms of tradition, the most basic laws and rules are all very similar to those of Christianity and Judaism. For example in what concerns God, afterlife, family, sexuality, social status, social issues, diet, etc.
Qur'an. 42:13
Despite all of these similarities, Islam still clashes with these (Christianity and Judaism) and other religions because like all other religious groups, Muslims believe that their religion is the true religion.
Now then, for that reason, call them to the Faith, and stand steadfast as thou art commanded, nor follow thou their vain desires; but say: "I believe in the Book which Allah has sent down; and I am commanded to judge justly between you. Allah is our Lord and your Lord: for us is the responsibility for our deeds, and for you for your deeds. There is no contention between us and you. Allah will bring us together, and to Him is our Final Goal.Tension and conflicts are inevitable.
Qur'an. 42:14-16.
Certain laws for freedom of religion have been created since the invasion led by the US in 2001. Now, in the Constitution of Afghanistan, while it says that “Afghanistan shall be an Islamic Republic”, it also says that, “Followers of other faiths shall be free within the bounds of law in the exercise and performance of their religious rights”.
