Beware of false thought, for false thought is the most untruth speech

The Prophet (may Allah's peace and blessings be upon him) prohibits and warns against some of what could lead to dissension and enmity among Muslims. This includes the following: "Zhann" (false thought): It is a baseless suspicion arising in the heart, and the Prophet (may Allah's peace and blessings be upon him) clarified that it is the falsest of speech. "Tahassus" (searching for faults): It is to look for others' flaws through the eye or the ear. "Tajassus"

(spying): It is searching for hidden affairs, and it is mostly used in a negative context. "Hasad" (envy): It is hating to see others enjoying a blessing. "Tadābur" (turning one's back on others): It is turning away from one another and refraining from greeting or visiting one's Muslim brother. "Tabāghud" (harboring hatred): It is malice and aversion such as harming others, frowning, and meeting people in a bad manner.

Then, the Prophet (may Allah's peace and blessings be upon him) said a comprehensive statement that guarantees maintaining good relations between Muslims, saying: "And be, O slaves of Allah, brothers". Brotherhood is a bond that unites people and enhances love and familiarity among them.
