Honestly in business is Commanded by God.

Some of the verses quoted in the video .

"And do not approach the property of the orphan except in the best manner until they reach maturity and GIVE FULL WEIGHT AND MEASURE WITH JUSTICE. We do not burden a soul beyond it's ability; and when you speak be just, even if against family, and fulfill your deal with God; this He has commanded you with that you may be mindful." - Quran 6:152

"And give full measure when you measure out, and weigh with a true balance; this is fair and better in the end." - Quran 17:35

"And to Midian (We sent) their brother Shu'aib. He said: O my people! serve God you have no god other than He; and DO NOT GIVE SHORT MEASURE AND WEIGHT, surely I see you in prosperity and surely I fear for you the punishment of an all-encompassing day.
And, O my people! give full measure and weight fairly, and do not cheat people of their things, and do not act corruptly in the land, making mischief:" -- Quran 11:84

"And to Midian (We sent) their brother Shu'aib. He said: O my people! serve God, you have no god other than Him; clear proof indeed has come to you from your Lord, therefore GIVE FULL MEASURE AND WEIGHT and do not diminish to people their things, and do not make corruption in the land after its reform; this is better for you if you are believers." - Quran 7:85

"And the chiefs of those who disbelieved from among his people said: If you follow Shu'aib, you shall then most surely be losers
Then the earthquake overtook them, so they became motionless bodies in their homes.
Those who called Shu'aib a liar were as though they had never lived therein; those who called Shu'aib a liar, they were the losers.
So he turned away from them and said: O my people! certainly I delivered to you the messages of my Lord and I gave you good advice; how shall I then be sorry for an unbelieving people?" - Quran 7:90-93

"These towns-- We relate to you some of their stories, and certainly their messengers came to them with clear arguments, but they would not believe in what they rejected at first; thus does God set a seal over the hearts of the unbelievers
And We did not find most of them true to the covenant, and We found most of them to be defiantly disobedient." -- Quran 7:101-102
