Business is mentioned in the Quran in these verses:

[2:282] O you who believe, when you transact a loan for any period, you shall write it down. An impartial scribe shall do the writing. No scribe shall refuse to perform this service, according to God’s teachings. He shall write, while the debtor dictates the terms. He shall observe God his Lord and never cheat. If the debtor is mentally incapable, or helpless, or cannot dictate, his guardian shall dictate equitably. Two men shall serve as witnesses; if not two men, then a man and two women whose testimony is acceptable to all. Thus, if one woman becomes biased, the other will remind her. It is the obligation of the witnesses to testify when called upon to do so. Do not tire of writing the details, no matter how long, including the time of repayment. This is equitable in the sight of God, assures better witnessing, and eliminates any doubts you may have. Business transactions that you execute on the spot need not be recorded, but have them witnessed. No scribe or witness shall be harmed on account of his services. If you harm them, it would be wickedness on your part. You shall observe God, and God will teach you. God is Omniscient.

[9:24] Proclaim: “If your parents, your children, your siblings, your spouses, your family, the money you have earned, a business you worry about, and the homes you cherish are more beloved to you than God and His messenger, and the striving in His cause, then just wait until God brings His judgment.” God does not guide the wicked people.

[11:87] They said, “O Shu`aib, does your religion dictate upon you that we must abandon our parents’ religion, or running our businesses in any manner we choose? Surely, you are known for being clement, wise.”

[24:37] People who are not distracted by business or trade from commemorating God; they observe the Contact Prayers (Salat), and give the obligatory charity (Zakat), and they are conscious of the day when the minds and the eyes will be horrified.

[56:82] Do you make it your business that you disbelieve?

[62:9] O you who believe, when the Congregational Prayer (Salat Al-Jumu`ah) is announced on Friday, you shall hasten to the commemoration of God, and drop all business. This is better for you, if you only knew.

[62:10] Once the prayer is completed, you may spread through the land to seek God’s bounties, and continue to remember God frequently, that you may succeed.

[62:11] When some of them come across a business deal, or some entertainment, they rush to it and leave you standing! Say, “What God possesses is far better than the entertainment or the business. God is the best Provider.”
