Don't nurse grudge and don't bid him out for raising the price and don't nurse aversion or enmity and don't enter into a transaction when the others have entered into that transaction and be as fellow-brothers and servants of Allah. A Muslim is the brother of a Muslim. He neither oppresses him nor humiliates him nor looks down upon him. The piety is here, (and while saying so) he pointed towards his chest thrice. It is a serious evil for a Muslim that he should look down upon his brother Muslim. All things of a Muslim are inviolable for his brother in faith: his blood, his wealth and his honour.
Hadith Commentary: The Book of Virtue, Enjoining Good Manners, and Joining of the Ties of Kinship
Sahih Muslim 2564 a - This profound hadith from Sahih Muslim encompasses comprehensive guidance for maintaining harmonious social relations and upholding the rights of fellow Muslims, establishing the foundation of Islamic brotherhood.
Prohibition of Grudges and Economic Exploitation
"Don't nurse grudge" - Scholars explain this as forbidding harboring resentment in one's heart against another Muslim, which corrupts spiritual purity and disrupts social harmony.
"Don't bid him out for raising the price" - Classical commentators interpret this as prohibiting najash (deceptive bidding), where one artificially inflates prices without genuine intention to purchase, thereby deceiving legitimate buyers.
Brotherhood in Islam
"Be as fellow-brothers and servants of Allah" - This establishes the dual relationship between Muslims: spiritual brotherhood and shared servitude to Allah, creating bonds stronger than mere blood relations.
"A Muslim is the brother of a Muslim" - Scholars emphasize this creates mutual rights and responsibilities, requiring protection of each other's dignity, property, and life.
Prohibited Behaviors
"He neither oppresses him nor humiliates him nor looks down upon him" - Classical scholars categorize these as: dhulm (oppression), ihana (humiliation), and khafd (looking down upon others), all violating the sanctity of Muslim brotherhood.
The Prophet's gesture pointing to his chest indicates true piety (taqwa) resides in the heart's purity, not external appearances.
Inviolable Rights of Muslims
"All things of a Muslim are inviolable" - Scholars identify three fundamental protections: blood (life), wealth (property), and honor (reputation and dignity).
This comprehensive protection forms the basis of Islamic social ethics, where every Muslim becomes a guardian of their brother's rights.
