Brotherhood among Muslims

On the authority of Abū Hurayra, may Allah be pleased with him, who said: The Messenger of Allah ﷺ said: Do not envy one another, do not inflate prices against one another, do not hate one another, do not turn your backs on one another, and do not undercut one another's sales; and be, O servants of Allah, brothers. The Muslim is the brother of the Muslim: he does not wrong him, nor forsake him, nor lie to him, nor despise him. Piety is here, and he pointed to his chest three times. It is enough evil for a person to despise his Muslim brother. All of the Muslim is inviolable to the Muslim: his blood, his property and his honour.
