The Quran as the Complete and Sufficient Source of Religious Law
One of the foundational principles of submission to God is that the Quran is complete, fully detailed, and sufficient as the sole source of religious law. This is not a human opinion; it is a declaration made by God Himself.
The Quran presents itself as:
• fully detailed
• complete
• perfect
• fully explained by God
• the only scripture to be followed for law
This clarity protects believers from the errors of past communities who added human traditions, clerical authority, and inherited customs to God’s religion.
God Declares the Quran Fully Detailed
The central verse on this topic is clear:
“Shall I seek other than God as a source of law, when He has revealed to you this book fully detailed?” (6:114)
This teaches us that:
• God alone is the source of religious law
• The Quran contains complete details for that law
• Seeking religious rulings from any other source violates His command
Fully Detailed for Guidance and Law
When the Quran describes itself as fully detailed, the context is guidance and religious law:
• moral commandments
• spiritual principles
• lawful and unlawful boundaries
• worship directed to God
• social justice and family law
• ethical conduct
• accountability and justice
God did not leave His religion incomplete or dependent on human authorities.
No Need for Secondary Sources
Since the Quran is fully detailed:
• no additional scripture is needed
• no biography is required to complete it
• no commentary is required to fill gaps
• no ritual manuals are necessary
If anything is required for salvation, righteousness, or obedience to God, it is already in the Quran.
What About Rituals?
Some notice that the Quran does not spell out procedural details for major rituals. This is consistent with the Quran’s narrative: all religious duties were given to Abraham.
These rituals were:
• known to all prophets
• practiced by their communities
• inherited in continuous tradition
Thus the Quran restores and purifies these rituals rather than reinventing them. It is fully detailed for law, while rituals remain Abrahamic practices already known.
Nothing Missing for Guidance
The Quran defines its completeness:
• “Fully explained in detail” (6:114)
• “A clear explanation of all things” (16:89)
• “Perfected and detailed” (11:1)
• “Nothing has been left out of the Book” (6:38)
These confirm that the Quran is not partial or dependent on external sources of authority.
God as the Teacher
The Quran emphasizes that God is the teacher of the scripture:
• God explains
• God clarifies
• God guides
• God provides meaning
Thus the Quran requires reflection, not intermediaries.
A Universal Scripture
A book that is universal, timeless, preserved, and complete must stand alone. Human sources can offer commentary and analysis, but cannot provide religious law. Only the Quran fulfills that role.
Conclusion
To affirm the Quran as fully detailed is to affirm that:
• God does not leave His religion incomplete
• The Quran contains all necessary laws and principles
• No additional scripture or tradition is required
• Abrahamic rituals are inherited, not reinvented
• The Quran is God’s final, complete, and preserved revelation
“Fully detailed” is a declaration of God’s authority and the perfection of His scripture.
