"Remember, there is no faith in him who is not trustworthy;

Islam orders the Muslim to be honest to himself and others. This order repeatedly comes in the Noble Qur'an and the sayings of Prophet Muhammad (SAWS). Islam orders the Muslim to tell the truth even if it is against the teller's interest. Orders him not to cheat or deceive other people. A Muslim is ordered by Allah to be honest in his words and deeds, privately and publicly alike.
The Qur'an as well as the Traditions of the Prophet are emphatic that a true Muslim is he who is honest and upright in his business and monetary transactions, keeps his word and fulfill his promises, shuns fraud and avoids deceit and perfidy, encroaches not upon the rights of others, nor takes part in wrongful litigation, does not give false evidence, and abstains from making dishonest money as from usury and graft. Whoever is not free from these vices is, according to the Qur'an and the Traditions, not a true believer but a renegade and a worthless transgressor.
"Remember, there is no faith in him who is not trustworthy;  Let us examine some of the relevant Quranic verses and traditions. A short verse of the Quran says:

"Oh ye who believe! Eat not up each other's property by unfair and dishonest means." (4:29)

The verse forbids Muslims against all unclean and corrupt means of making money, such as, dishonest trading, embezzlement, gambling, speculation and bribery. Then there are verses in which these hateful practices are dealt with one by one. For instance, a severe warning is given in the following verse to traders who cheat in weighing:

"Woe to those that deal in fraud, - those who, when they have to receive by measure from men, exact full measure, but when they have to give by measure or weight to men, give less than due. Do they not think that they will be called to account- on a Mighty Day when (all) mankind will stand before the Lord of the Worlds." (133: 1-6)

In the same way, the under mentioned verse exhorts Muslims to be very particular about their trusts and about other people's rights.

"Allah doth command you to render back your trust, to those to whom they are due."(4:58)

At two places in the Quran a chief distinguishing feature of Muslims is said to be that they are:

"Those who faithfully observe their trusts and their covenants."(24:8)

The Prophet often used to say in his sermons:

"Remember, there is no faith in him who is not trustworthy; there is no place for him in religion who cares not for his pledged word or promise."

Another tradition says:" The signs of a hypocrite are three: when he speaks, he is false, when he promises, he fails; and when he is trusted, he plays false."

Condemning those who cheat in business the sacred Prophet has said:

"He who cheats is not of us. Deceitfulness and fraud are things that lead one to Hell."

The Prophet of Allah once came upon a heap of corn in the market of Medina and thrust his hand onto it. His fingers felt damp. On being asked, the trader replied that rain had fallen upon it. The Prophet observed,

"Why did you not then keep (the wet portion of) it above the dry corn, so that men may see it? He who deceives, is not one of us."

Thus traders who deceive by showing to customers a false sample or by concealing from them the defects of the article they offer for sale are not true Muslims in the judgment of the Holy Prophet and, God-forbidding, they are going to end up in hell. Another tradition says:

"The seller must explain to the buyer the defects, if any, in the quality of the article offered for sale. Should this not be done, the seller will permanently be caught in the Wrath of Allah (according to another narrator the exact words, ‘he will always be cursed by the angels')."

In short, all manner of deceit and dishonesty in business is prohibited in Islam. It has been proclaimed to be an act worthy of unqualified condemnation. The Holy Prophet has expressed his strong dislike for those who do so. He has said he will have nothing to do with them; they do not belong to him.

Likewise, bribery and usury, although might be practiced by mutual consent and agreement, are totally disallowed to Muslims and those who are guilty of them have been condemned squarely in the traditions. A well-known tradition on usury reads:

"The curse of Allah rests on him who offers loan on usurious terms, and on him who receives, and on those who are witnesses to the transaction, and on the writer who writes the deed thereof."

As for bribery, the Prophet ) according to a tradition, "condemned alike the giver of bribes, and the taker of bribes in deciding cases."

A tradition goes even to the extent of saying that,

"If a person made a recommendation for anyone in a just manner and gratified party gave him something as a gift (in return for it) and he accepted it, then he committed a grave error (meaning that it, too, is a form of bribery)."

Worse still is the usurpation of another's property by force or fraud or dishonest litigation. We have it on the authority of the Prophet that:

"Whoever occupies land belonging to another unjustly will be sunk into the ground along with the plot of land on the Doomsday till he reaches the lowest layer of the earth."

"He who acquires the property of a Muslim unjustly by taking a false oath (before an Officer) is debarred by Allah from entering Paradise and the Fire of Hell is made inevitable for him." On hearing it a Companion is reported to have replied, " Yes, even if it be a twig of Pilo (a plant which grows wild. Its twigs are used for cleaning the teeth).

The Prophet again, is reported to have warned a person who was very fond of entering into litigation with others in these strong words, "Remember, he who will obtain the property of another by swearing a false oath will appear as a leper before Allah (on the Day of Judgement).

And, again:

"Whoever laid a claim on a thing that was not his is not of us. He will do well to reserve a place for himself in the Hell."

It is narrated that one day, after the morning prayers the Holy Prophet stood up and said thrice with great feeling that, " Perjury has been made the equivalent of Polytheism

Nearly everyone agrees, Honesty is the best policy. Yet, when push comes to shove, many people tell a little white lie to avoid hurting someone's feelings, or facing oneself. This article discusses the rationale of little white lies, and if - when a white lie is acceptable.

No matter how insignificant you might think a 'little white lie' (dishonesty) has on the relationship, the energy of a 'little white lie' looms between you and the other person. You might argue that 'little white lies' (untruths) are harmless. However, they are like small cracks that weaken the overall structure in the long term. Even giving someone a false compliment or ostensibly protecting someone can create problems later when the alternate reality you created becomes the basis for further interactions. Even though all future actions may be honest, the underlying unstable foundation of a 'little white lie,' (dishonesty) will threaten to derail an otherwise good relationship. This then leads to further energy being spent on keeping things hidden, working to remember the 'little white lies' you have told and fearing the consequences of being found out. Your relationships then becomes a tiring and draining experience.

Speaking and living your truth, involves risking, and among other things, the possibility of rejection. However, when you allow yourself to follow the honest flow of life, you are supported by the universal law of cause and effect. You can then use your energy to cultivate physical, emotional and spiritual well-being and to create your dreams, rather than leaving yourself vulnerable to being drained and overwhelmed with keeping the web of dishonest puzzle pieces coherent.
When you speak the truth, you affirm what already is. Speaking your truth is analogous to using a paddle when the stream is already moving the same direction. You are already supported by the universe and its energy flow, so you do not need to exert extraordinary energy, thus leaving more energy for other pursuits. Energetically, dishonesty redirects your energy against the flow, which requires extra effort. In addition, dishonesty creates an alternate reality that requires further energetic attention to be maintained.

Thus, you can readily see that you are best served when you work with the flow of the universe.
You can make the choice to be free of the burden of dishonesty at any time. Today is the first day of the rest of your life--Begin today to choose honesty in every interaction. Bringing the nurturing power of the universe's energy into your life brings lasting positive results.

Of course, one of the components of honesty is refusing to submit to temptations and impulses. In Ramadan, the Muslim is thirsty, but he does not drink; he is hungry, but he does not eat. In Ramadan, water is spatially near but psychologically far from the Muslim; water is near to the Muslim but far from his desire. This is a practical exercise of self-control and internal honesty.

So, Islam instructs the Muslim to be honest and trains him to be so. The outcome is a healthy self and a healthy social atmosphere that leads to the happiness of both the individual and the group.
