On the authority of Abu Sa’eed al-Khudree (ra) who said: I heard the Messenger of Allah (saw) say, “Whoso- ever of you sees an evil, let him change it with his hand; and if he is not able to do so, then [let him change it] with his tongue; and if he is not able to do so, then with his heart — and that is the weakest of faith.” [Muslim]

أَبِي سَعِيدٍ الْخُدْرِيّ رَضِيَ اللهُ عَنْهُ قَالَ سَمِعْت رَسُولَ اللَّهِ صلى الله عليه و سلم يَقُولُ:

“مَنْ رَأَى مِنْكُمْ مُنْكَرًا فَلْيُغَيِّرْهُ بِيَدِهِ، فَإِنْ لَمْ يَسْتَطِعْ فَبِلِسَانِهِ، فَإِنْ لَمْ يَسْتَطِعْ فَبِقَلْبِهِ، وَذَلِكَ أَضْعَفُ الْإِيمَانِ” .

[رَوَاهُ مُسْلِمٌ].

On the authority of Abu Hurayrah (ra) who said: The Messenger of Allah (saw) said, “Do not envy one another, and do not inflate prices for one another, and do not hate one another, and do not turn away from one another, and do not undercut one another in trade, but [rather] be slaves of Allah and brothers [amongst yourselves]. A Muslim is the brother of a Muslim: he does not oppress him, nor does he fail him, nor does he lie to him, nor does he hold him in contempt. Taqwa (piety) is right here [and he pointed to his chest three times]. It is evil enough for a man to hold his brother Muslim in contempt. The whole of a Muslim is inviolable for another Muslim: his blood, his property, and his honour.” (Muslim]
