My apologies for forgetting to add some of which is not Halal. Because I can't edit/modify, I have to add them here.
Concerning divorce, Q[2:228, 229, 230]
Forced Marriage, Q[4:19]
Hisham (Hicham9):
Everything which is not declared as Haram or "not Halal" in the Quran is Halal, but it does not mean that we must do/eat all of them.
As I said
Can we do something which is bad/wrong/harmful but not Haram? No, Q[91:8,9,10]
according to Q[91:8-10], we, humans, know what is right and what is wrong, and also from experience and/or science we know what type of food/drink is harmful and what type of food/drink is harmless or beneficial, without any need for a book from God. Therefore, it is not necessary to search the whole list of good and bad in the Quran. Some of acts/foods which are not Haram but wrong/harmful are mentioned in the Quran; for instance, God has not declared intoxicates and gambling Haram, but for some given reasons (Q[5:91], Q[2:219]) wants us to avoid them for our own good (Q[5:90]). I think, to be a good ethical person, one should not just stick to the commands of God and/or pressure of society.
