It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Beware of oppression! For oppression will be (many) darknesses on the Day of Resurrection. Avoid foul speech, for indeed Allah Almighty does not like abusive and obscene language. And beware of intense love for wealth! For this very thing incited those before you to such an extent that they considered the forbidden as lawful, shed blood, and severed ties of kinship.

It is narrated from Sayyiduna Abdullah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: … Then a similar hadith was narrated, however, the words "al-fuhsh wa al-tafahhush" were not mentioned.

Syedna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Do not envy one another, do not artificially inflate prices, do not harbor hatred against one another, avoid mutual severance of relations and enmity, and let no one make an offer over the offer of his brother. O servants of Allah! Become brothers. A Muslim is the brother of a Muslim; he does not oppress him, nor does he disgrace him, nor does he look down upon him. Piety is here, and then he (peace and blessings be upon him) pointed towards his blessed chest and repeated this action three times. It is enough evil (or shirk) for a man that he considers his Muslim brother insignificant. The blood, wealth, and honor of every Muslim are forbidden to every other Muslim.

It is narrated from Sayyiduna Wathilah bin Asqa’ (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: … then the words of the mentioned hadith from "The Muslim is the brother of the Muslim" to the end were stated.

Narrated by Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: Whoever has wronged his brother regarding his wealth or honor, let him settle it with him now, before the day comes when he will be held accountable and there will be neither dinar nor dirham. (On that day, the matter will be settled in such a way that) if he (the oppressor) has good deeds, they will be taken from him, and if he does not have good deeds, then the bad deeds of the (oppressed) people will be placed upon him.

Is a man’s love for his own people considered ‘asabiyyah (tribalism)? He (peace and blessings be upon him) replied: No, ‘asabiyyah is when a person helps his people in wrongdoing.

Narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever helps his relatives in something unjust, his example is like that of a camel which is thrown into a well and then pulled out by its tail.
