What are the morals of trade as advised in the Qur'an?

A believer performs every deed in order to earn the good pleasure of Allah. No matter what he is engaged in, he does not let it divert him from his real aim. Allah has mentioned in the Qur’an that trade or commerce does not make believers forget their real goal:

There are men who proclaim His glory morning and evening, not distracted by trade or commerce from the remembrance of Allah and the establishment of prayer and the payment of alms; fearing a day when all hearts and eyes will be in turmoil. (Surat an-Nur, 36-37)

Allah wants believers to be of virtuous character, and believers strive to fulfil the requirements of this character whatever activity they are engaged in. Hence, they are honest, sincere, diligent, fair and modest even while they are conducting trade. Their attention is again focused on the pleasure of Allah and on the limits of what He permits and what He forbids. Besides this, Allah has also commanded believers not to encroach on the rights of others, to give full measure and full weight, and not to cheat people of their belongings (Surah Hud, 85).

In Surat al-Isra’, Allah states that it is better to be honest, to be fair and to please Him by means of exhibiting such good behaviour:

Give full measure when you measure and weigh with a level balance. That is better and gives the best result. (Surat al-Isra 35)
