Prohibition of Arrogance and Oppression

Imam Al-Nawawi’s Riyad-us-Saliheen
Chapter 279
Prohibition of Arrogance and Oppression

Allah, the Exalted, says:

So ascribe not purity to yourselves. He knows best him who fears Allah and keeps his duty to Him [i.e., those who are Al-Muttaqun (the pious)].” (53:32)

The way (of blame) is only against those who oppress men and wrongly rebel in the earth without justification; for such there will be a painful torment.” (42:42)

1589. `Iyad bin Himar (May Allah be pleased with him) said: The Messenger of Allah (sallallaahu ’alayhi wa sallam) said, “Verily, Allah has revealed to me that you should adopt humility. So that no one may wrong another and no one may be disdainful and haughty towards another.”
[Muslim].

1590. Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah (sallallaahu ’alayhi wa sallam) said, “When a person says: `People have been ruined, he is the one to be ruined the most.”’
[Muslim]

In another version: “He himself is the most ruined among them.”
