You wrote: “The Quran cannot tell us everything they did and yes or no to follow it, so it GIVES US THE GENERAL RULE THAT IF IT IS AUTHORISED BY QURAN, DO IT, IF NOT, THEN REJECT IT, or do not make it a religious obligation.”
The above statement of yours in CAPITAL is a blanket statement. PLEASE QUOTE THE VERSES THAT STATE THE ABOVE “GENERAL RULE” AS CITED BY YOU.
What you cited in this post to support your untenable thesis are verses 2:213, 3:23, and 4:105. 3:23 and 4:105 are quoted out of context and don’t support your thesis as outlined above, 2:213 is the only one to be elaborated further.
The word “Hakama” (from which Hukm in 2:213 is derived) means: to prevent, to restrain someone from acting in an evil, corrupt, and wrongful way. From this words, government, judicial authority, judge, etc. are inferred because these entities are needed to restrain someone from acting in wrongful way. The word “HUKM” in 2:213 originally signifies the PREVENTION AND RESTRAINT, hence, judgement and/or judicial decision. See both Lane and Lughat.
Question is: when mankind was one nation/community, why did God send the Book, for what purpose? It is obvious, the book elaborates and sets the limits of what is evil, what is corrupt, what is wrongful, what is unlawful, etc., so that people know the limits and restrain themselves from acting in evil and wrongful ways, thereby not trampling upon the rights of others, OR, those who render the judgement between people can use the book as basis to do so. DID YOU FIND “CIRCUMCISION” DESCRIBED AS EVIL, CORRUPT, and WRONGFUL ANYWHERE IN THE BOOK? If NOT and surely NOT, you cannot use 2:213 to support your UNTENABLE GENERAL RULE.
