Rules are mentioned in the Quran in these verses:
[2:220] upon this life and the Hereafter. And they ask you about the orphans: say, “Bringing them up as righteous persons is the best you can do for them. If you mix their property with yours, you shall treat them as family members.” God knows the righteous and the wicked. Had God willed, He could have imposed harsher rules upon you. God is Almighty, Most Wise.
[16:76] And God cites the example of two men: one is dumb, lacks the ability to do anything, is totally dependent on his master – whichever way he directs him, he cannot produce anything good. Is he equal to one who rules with justice, and is guided in the right path?
[27:78] Your Lord is the One who judges among them in accordance with His rules. He is the Almighty, the Omniscient.
[30:46] Among His proofs is that He sends the winds with good omen, to shower you with His mercy, and to allow the ships to run in the sea in accordance with His rules, and for you to seek His bounties (through commerce), that you may be appreciative.
[60:10] O you who believe, when believing women (abandon the enemy and) ask for asylum with you, you shall test them. God is fully aware of their belief. Once you establish that they are believers, you shall not return them to the disbelievers. They are not lawful to remain married to them, nor shall the disbelievers be allowed to marry them. Give back the dowries that the disbelievers have paid. You commit no error by marrying them, so long as you pay them their due dowries. Do not keep disbelieving wives (if they wish to join the enemy). You may ask them for the dowry you had paid, and they may ask for what they paid. This is God’s rule; He rules among you. God is Omniscient, Most Wise.
