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.
