Khianah refers to "Treachery" or "Breach of Trust," which is the opposite of "Amanah" (trustworthiness). In Islam, keeping one's word and fulfilling covenants,whether with God or with fellow human beings,is a religious obligation. Khianah is described as one of the signs of a hypocrite, alongside lying and breaking promises. It includes betraying one's spouse, mishandling entrusted wealth, or leaking secrets that could harm the community.
The Quran commands: "Indeed, Allah commands you to render trusts to whom they are due" (4:58). This verse establishes fulfilling trusts as a divine command, not merely a social convention. The opposite,khianah,is a major sin that indicates corrupt faith. The Prophet described the hypocrite (munafiq) with three traits: lying, breaking promises, and betrayal of trust (khianah). He said: "The signs of a hypocrite are three: when he speaks, he lies; when he makes a promise, he breaks it; and when he is entrusted, he betrays" (Bukhari, Muslim).
In business and finance, khianah is particularly destructive. The Prophet said: "The trustworthy merchant will be with the prophets, the truthful, and the martyrs on the Day of Judgment" (Tirmidhi). Conversely, betrayal in business,cheating, concealing defects, or breaching contracts,is a form of khianah. In personal relationships, khianah is devastating. The Prophet said: "The worst betrayal is when a man betrays his wife's trust" (Tabarani).
The cure for khianah is to cultivate amanah (trustworthiness). The believer sees everything entrusted to them,wealth, secrets, positions, relationships,as a trust from Allah. They understand that they will be questioned about how they fulfilled these trusts. Repentance from khianah requires: returning the trust to its rightful owner; making amends; and resolving never to betray trust again. The Prophet said: "Fulfill the trust to the one who entrusted you, and do not betray the one who betrays you" (Abu Dawud). Even if others are dishonest, the believer remains trustworthy.
