Riyad as-Salihin, The Book of Miscellany
Book 1, Hadith 235
Narrated 'Abu Hurairah (ra):
Messenger of Allah (pbuh) said, "Do not envy one another; do not inflate prices by overbidding against one another; do not hate one another; do not harbour malice against one another; and do not enter into commercial transaction when others have entered into that (transaction); but be you, O slaves of Allah, as brothers. A Muslim is the brother of another Muslim; he neither oppresses him nor does he look down upon him, nor does he humiliate him. Piety is here, (and he pointed to his chest three times). It is enough evil for a Muslim to hold his brother Muslim in contempt. All things of a Muslim are inviolable for his brother-in-faith: his blood, his property and his honour".[Muslim].

Narrated 'Anas (ra):
Messenger of Allah (pbuh) said, "Help your brother, whether he is an oppressor or is oppressed". A man enquired: "O Messenger of Allah! I help him when he is oppressed, but how can I help him when he is an oppressor?" He (pbuh) said, "You can keep him from committing oppression. That will be your help to him".[Al-Bukhari and Muslim].
