Please allow me to re-state what has been said in this thread, so point out if I misunderstood.
Based on the examples provided by Mr. Nom:
In reference to verse 4:82, he points out that the word "akhtilāfāan" (divergences/contradictions) occurs only once in the Quran. He suggests that this lack of repetition indicates that the Quran is free from contradictions.
He also mentions verse 75:3-4, which discusses the restoration of a person's fingertips. He argues that individual fingerprints are unique, and if identical twins did not have unique fingerprints, it would contradict this verse.
Another example he presents relates to inheritance laws mentioned in verse 4:12. He discusses the different shares allocated to spouses, mothers, fathers, and the concept of taking from the whole or paying off others first. He points out that some interpretations may result in incorrect distributions of inheritance.
In essence, Mr. Nom is drawing attention to specific verses and suggesting that these examples demonstrate either the absence of contradictions in the Quran or potential discrepancies in interpretation.
Coming back the original question of this thread, I feel that through deep contemplation and reflection, it becomes evident that there exists a clear distinction between human emotions and divine legislation. Human emotions are characterized by inconsistency, where individuals may express one thing verbally, engage in different actions during the day, and harbor contrasting thoughts in their hearts. However, the legislation of God, the Quran, is devoid of any contradictions. It presents a unified reality from various perspectives. If it were the words of someone other than God, it would undoubtedly contain numerous discrepancies (2:23).
Despite the presentation of compelling evidence and proofs, if one finds oneself in doubt or psychological confusion regarding the authenticity of the code of life bestowed upon us through the intercession of the Prophet, the simplest way to dispel such doubt is to propose an alternative plan for human life. Assemble all the intellectuals, thinkers, civilizational and political authorities of your society into a committee, excluding divine revelation alone, and challenge them to produce even a single chapter similar to the Quran. If you genuinely believe that you are incapable of determining whether this code is from God or not, and if you are merely harboring doubts and suspicions to protect your vested interests, then you must indeed accept this challenge (11:13; 10:38).
It is important to address the question of whether this challenge persists today or was solely applicable during the lifetime of the Prophet. The challenge was initially presented during the time of the Prophet as a means to affirm the divine origin of the Quran. As the Prophet was the recipient of direct revelation, he served as the ultimate authority to verify and authenticate any attempts to produce a similar scripture. However, in the present day, without the presence of the Prophet, the challenge no longer holds the same weight. While the Quran remains as a testament to its divine nature, the challenge itself was specific to the historical context of the Prophet's era.
