The people of the thick trees also did wrong.
Shuayb's people, the dwellers of Al-Aykah
Ibn Kathir says the dwellers of Al-Aykah, meaning intertwined trees, were the people of Shuayb. Their evildoing included shirk, banditry and cheating in weights and measures. They lived near Lut's people, at a later time.
You round the invoice up a little. You sell the phone without mentioning the cracked camera. You pad your hours. Small cheats in the scale. This verse puts dishonest trade beside shirk.
Business is business; a little rounding up hurts no one.
Cheating in a deal is a real wrong that Allah lists alongside the biggest ones.
Check one transaction, invoice or sale you have open and make it completely honest.
