Islam is an Arabic word which literally means submission of one’s free will to the Will of God. It is known as Ad Deeenul Fitra (the natural way of life). Islam is to man what Maxwell’s equations are for electromagnetism, or what Kepler’s laws are for planetary motion. It is the natural law of mankind. By worshiping the One God, we are divinely inspired to make correct decisions through inspiration from Him, while acting according to divinely prescribed behavior taught by messengers and prophets sent by God, the last of whom was Prophet Muhammad (SWAS) who was sent to teach the final version of ideal behavior to all of humanity.
When we live a clean life inside and out and follow the natural way in the pure thought patterns in our intentions, and our actions and we are not impressed by anyone or anything other than the One God, rather we are awed by His Majesty and Power in controlling the entire universe and us, we have no recourse by to fall in prostration contemplating on His Might. Once we realize that there is no other person, thing, concept, or entity to rely on than Him, we start worshiping Him alone. He guides us without seeking anyone’s help through instinct, and epiphanies, by making all positive forces in the universe favor what we aspire to do because we are doing it in pure sincerity for His pleasure alone, to help bring humanity from darkness to light.
The only creature (except for genies) who have free will, will lovingly and willingly use that free will to either live unnaturally or naturally, make the choice of natural living, removing oppression from their own souls, their communities, their environment, and the planet. It does not matter if we develop the best technologies in the world to address our looming problems, including carbonization, unless we fix ourselves first, despite the amount of capital we throw at them, we will not be able to solve them satisfactorily.
Each of the world’s major religious traditions were from the same natural way of life that was taught through divine scriptures like the scrolls through Abraham, psalms through David, Torah through Moses, Gospel through Jesus, Quran through Muhammed, and other scriptures that might not be mentioned in our sources that may have been sent to the global population living outside the Middle East.
All religions help in spirituality, but there is the aspect of being inspired by One Source which is strictly not there anymore due to historical distortions that aggregated over the years. Today, perhaps only Judaism and Islam are truly monotheistic. Unfortunately, the fact that the Children of Israel were favored by God historically for guidance through the sending of so many prophets (some of whom were Jacob, Joseph, David, Solomon, Zakariah, John the Baptist, and Jesus) we find that Judaism today has become an exclusive religion. By its own definition, it is not for the rest of humanity.
In contrast, Islam is the same religion prescribed for Adam when he descended on the earth from Paradise, Noah when he preached to his nation, Jacob who taught it to his children, Joseph through which he could solve the greatest problem in Egypt, David through which he could establish it in Canaan, Solomon through which he could rule by God’s law over vast areas subjugating natural forces, Jesus through which he could heal the leper, restore sight to the blind, and bring back the dead to life by God’s permission, and Muhammad (SWAS) through which (without any exaggeration) he became the best of creation.

The Quran mentions about 25 messengers and prophets by name (mostly Biblical and ancient Arabian) but in some accounts of Prophet Muhammed (SWAS) there can be about a total of 124,000 who might have been sent to all pockets of civilization, e.g. African, Native American, Aboriginal, Chinese, European, Indian, and Oceanian. Thus the natural way of life was prescribed to each ancient civilization through their human role models who were to emulate (but not to take as their god), and perhaps a scripture so that everyone could willingly live in peace with themselves, their communities, their environments, and their planet. We still find remnants of natural living in the very tiny pockets of aboriginal people living integrated with nature, isolated from modernity.
Although the natural way of life has been the same throughout humanity, if humanity chose it for themselves, i.e. worship only the One God, while following behavior exemplified by the prophets and messengers, Nevertheless, the natural law has changed from time to time and community to community throughout history, until the final natural law was prescribed to all of humanity through Prophet Muhammed (SWAS).
Today, Islam is the only divine religion whose sources are still authentic and intact. In fact, it was the corruption in the sources of past religious traditions to justify new dogmas introduced by the custodians of those religious traditions that caused them to deviate from natural living. Islamic principles are based on mainly two divine sources. The first is the Quran which is the actual speech of God. The original was not in a written form but it was actual words, a recitation that was memorized and later compiled in book form. The second is what Prophet Muhammed (SWAS) taught in terms of his behavior and words. This information is extensively recorded, verified, and carefully graded so that it is very obvious what is authentic and what is not.
The third source of Islamic law is consensus (ijmaa) of Islamic scholars, in which issues that do not have clear solutions in the Quran and Prophetic practice and are resolved through the consensus of scholars. The fourth source of Islamic law is analogous reasoning (qiyaas) in which conclusions on an issue are derived by studying and applying the same methodology of resolving a similar issue in Islamic law.
Some of the guidelines used to make Islamic laws include what is good in terms of public interest in a matter, the opinion of the Qadhi (Islamic judge), the practices of early Muslim generations, as well as the local customs of where the law is being applied. A combination of all these together makes a law that is very dynamic and constantly growing to fulfill needs completely.
