Sidq is truthfulness. Amanah is trustworthiness. Together they are the character that made Makkah call Muhammad (peace and blessings be upon him) al-Amin before he called them to Tawhid. A Muslim who lies in trade, leaks secrets, and cheats hours at work has a hole that salah does not automatically fill. This article explains the Quranic and prophetic emphasis on truth and trusts, lying, promises, and how to repair a record of dishonesty. It is for learning, not a fatwa on a specific contract.
See akhlaq and Islamic finance.
Truth in speech and in selling
Allah commands the believers to be with the truthful (see Quran 9:119). The Prophet (peace be upon him) said that truthfulness leads to righteousness and righteousness leads to Paradise, while lying leads to wickedness and the Fire, as in Sahih al-Bukhari and Sahih Muslim. He forbade cheating. He said that whoever cheats is not of us, as in Sahih Muslim. A “white lie” in business is still a lie unless it falls under the narrow exceptions the scholars mention, such as reconciling two people with care. Do not expand the exception until it swallows your personality.
Amanah
Trusts include money, secrets, jobs, and positions in the mosque. The hypocrite’s signs include betraying a trust, as in the sahih hadith. If you are given a role, do it or leave it. Do not take a salary for work you did not do. Do not use a charity’s funds as a personal wallet.
Promises
Keep them. If you cannot, apologise and repair. A culture of “inshaAllah” as a polite no without meaning is not the Sunnah of the truthful.
Repair
If you lied, confess where a right is due, return money, and speak true from today. Tawbah is not a caption. It is a change of path.
Frequently asked questions

And Allah knows best.
