Sharia is a term that is associated with Islam. All over the Islamic world, Sharia is defined to be the subject or division of issuing Islamic laws. The establishment of Islamic Sharia in all Islamic countries has been always the work of man.
Religious leaders/Imams/Ulamaa/Scholars have always taken the responsibility to compile data to come up with the Sharia Laws. They have assigned themselves to be the guardians of religion and keepers of God's laws. They trained and brain-washed their audience. Although Quran has been always claimed to be their prominent source, the belief that it cannot stand alone as a fully detailed and complete source of divine laws has brought the man-made, Hadith and Sunna books at their disposal as a second source besides the divine word of God for Sharia.
Then, over the years, the human thirst for control and power have played a significant part in formulating and editing Sharia. Religious officials have been tempted to inject their very own interpretations and opinions to those laws to serve their own agendas! Thus, the consensus of those religious officials in one region has become an added, third source for all sorts of false issuings in the name of Islam. Sharia laws have become variable sets of laws within the same country depending on who is in charge, and would also sound different from one Islamic country to another! Many laws that affect economy, politics, justice system, marriage, divorce, inheritance, and religious rituals such as charity have been invented and imposed leading to all the chaos and the inhumane practices all over the world by the hands of Muslims or against them.
The image of God's authorized religion (3:19,85) has been tarnished and His message has been attacked because of the propaganda of the so-called Islamic sharia that mostly goes against human nature and contradicts the true Islamic laws issued by God in Quran. Moreover, different patterns of contradicting sharia laws of different Islamic regions have been publicized and taught in theology and world religions' classes all over the world only to muddy Islam and add more confusion about the divinity of Quran.
Ironically, Quran mentions all three words - Sharia, Hadith , and Sunna - but in a very different context from the one established by the scholars. Additionally, Quran warns us against following any personal opinions instead of God's teachings and sacred laws (28:50, 47:14) . God is fully aware of how subsequent generations after the revelation of Quran will come up with their own sharia and with their own sources for its laws. Therefore, He insisted on teaching us in Quran the true sharia. He indicated to us that religious scholars have done injustice to their souls and to His truth. They have declared that Quran alone is not enough while God testifies it is complete (6:115), perfect (11:1, 2:2) , fully detailed (6:114), has the explanations of everything (16:89), has the details of everything (12:111), and has all that we need for our salvation (6:51).
The root for the word sharia is "sha ra aa" and it means : to issue laws and practices. The root along with some of its derivatives are mentioned in Quran three times (42:13, 42:21, and 5:48). In addition to that, the word "sharia", itself, is mentioned once in 45:18. In all four verses, God is stating in black and white He is the ONLY entity to issue laws and practices through His scriptures, and that Quran is the ONLY documented divine sharia Muslims/Submitters must follow:
Only One Religion
Monotheists vs Idol Worshipers [42:13] He decreed (sharaa lakum) for you the same religion decreed for Noah, and what we inspired to you, and what we decreed for Abraham, Moses, and Jesus: "You shall uphold this one religion, and do not divide it." The idol worshipers will greatly resent what you invite them to do. GOD redeems to Himself whomever He wills; He guides to Himself only those who totally submit.
The Idols: Innovating New Religious Laws [42:21] They follow idols who decree for them (sharaau lahum) religious laws never authorized by GOD. If it were not for the predetermined decision, they would have been judged immediately. Indeed, the transgressors have incurred a painful retribution.*
Quran: The Ultimate Reference [5:48] Then we revealed to you this scripture, truthfully, confirming previous scriptures, and superseding them. You shall rule among them in accordance with GOD's revelations, and do not follow their wishes if they differ from the truth that came to you. For each of you, we have decreed laws (sheraah) and different rites. Had GOD willed, He could have made you one congregation. But He thus puts you to the test through the revelations He has given each of you. You shall compete in righteousness. To GOD is your final destiny - all of you - then He will inform you of everything you had disputed.
[45:17] We have given them herein clear commandments. Ironically, they did not dispute this until the knowledge had come to them. This is due to jealousy on their part. Surely, your Lord will judge them on the Day of Resurrection regarding everything they have disputed.
[45:18] We then appointed you to establish the correct laws (sharia); you shall follow this, and do not follow the wishes of those who do not know.
Similarly, the words Hadith and Sunna are used in Quran to warn us against their upcoming, false attribution to Prophet Muhammad or our religion. The word Hadith (narration) occurs to either refer to Quran itself (39:23, 45:6, 68:44, 77:50) or to point out that there should be no other hadith (narration) besides Quran to be followed (7:185, 12:111, 31:6, 52:34) . As for the word Sunna (system or way of life), it is interesting to note that it is mentioned 14 times in Quran. Eleven out of the fourteen are referring to God's unchangeable Sunna (15:13, 17:77-twice, 33:38, 33:62 -twice, 35:43 -twice, 40:85, 48:23 -twice). The other three are referring to the sunna or the system of other entities and how we must pay attention to the bad consequences we face when we follow these other Sunnas (8:38, 18:55, and 35:43). This only invalidates any common use or implications of Hadith, or Sunna, specially as a source for sharia laws that rule and control.
Quran: Fully Detailed [6:114] Shall I seek other than GOD as a source of law, when He has revealed to you this book fully detailed?* Those who received the scripture recognize that it has been revealed from your Lord, truthfully. You shall not harbor any doubt.
[18:27] You shall recite what is revealed to you of your Lord's scripture. Nothing shall abrogate His words, and you shall not find any other source beside it.
[25:27] The day will come when the transgressor will bite his hands (in anguish) and say, "Alas, I wish I had followed the path with the messenger.
[25:28] "Alas, woe to me, I wish I did not take that person as a friend.
[25:29] "He has led me away from the message after it came to me. Indeed, the devil lets down his human victims."
[25:30] The messenger said, "My Lord, my people have deserted this Quran."
Peaceful Friday, salaam, and God bless.
