The Messenger of Allah ﷺ said: “Do not envy one another, do not bid against one another ˹to raise the price˺, do not hold grudges for another, do not turn your backs on one another, and do not sell over one another’s sale. Be servants of Allah as brothers. A Muslim is the brother of a Muslim: he does not wrong him, nor abandon 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. Everything of a Muslim is inviolable to another Muslim: his blood, his wealth, and his honor.”
