Doubt - Suspicion - Slander - Backbiting
A suspicion is the feeling that someone(a person) has a intention of doing wrong or is doing wrong to you.
Doubt is a feeling of uncertainty or lack of conviction because of two or more possibilities. Doubt means that we have different possibilities in the mind about the correctness or otherwise about a thing. If we weigh the possibilities we would find that they are of equal or unequal weight.
If one possibility is heavier, then the other possibilities, it results in presumption or supposition. When one possibility is lighter in comparison to the other then it is called apprehension. When a possibility has more weight than the other possibilities it results in conviction. When there are no other possibilities and no doubt, it results in certainty. Certainty gives safety, clam and peace of mind.
In the Tasawwuff sufi/irfan traditions Suspicion in most cases and Doubt in some cases are an indication that the heart (Qalb) is affected with a spiritual disease.
Suspicion increases the fear of people, pessimism and misguided thinking, hence resulting in unwanted anger, anxiety, sadness and resentment, slander and backbiting that destroys the body, mind, and soul. Suspicion robs health from the body, peace from the mind, and weakens the soul.
There is a verse in the quran which reads "O you who believe! Avoid much suspicion, for some suspicion is a grave sin; and do not spy (on one another), nor backbite (against one another). Would any of you love to eat the flesh of his dead brother? - 49:12 - Quran
The Quran calls to avoid suspicion (zann, also translated "conjecture"), spying on others to find faults (tajassus), and backbiting (ghibah). The Quran considers backbiting and slandering someone in their absence so sinful and abhorrent that it is compared to "eating the flesh of ones brother".
Suspicion leads to jealousy, hatred, slander and backbiting. slander and backbiting are repugnant to the intelligence, and to the heart, to humanity and conscience, to human nature, and social brotherhood/sisterhood.
Slander and Backbiting is a shameful weapon and most used by people of enmity, envy, and obstinacy; no self-respecting, honorable human being would ever demean themselves by resorting to such a vile weapon.
Backbiting consists in speaking about an absent person in a way that would repel or annoy him or her if he or she were present and were to hear. If the words uttered are true, that is backbiting; if they are not, this is both backbiting and slander and, therefore, is a doubly loathsome sinful behaviour.
Avoiding Suspicion, slander, backbiting to keep a peaceful and calm heart and mind.
