It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Do not envy one another, do not deceive one another, do not bear malice against one another, do not sever relations with one another, and none of you should make a sale over the sale of his brother. And O servants of Allah! Be brothers to one another. A Muslim is the brother of a Muslim; he does not oppress him, does not leave him helpless, does not despise him. Piety is here—saying this, the Noble Prophet (peace and blessings be upon him) pointed to his blessed chest three times. It is enough evil for a Muslim that he considers his Muslim brother insignificant. The life, wealth, and honor of every Muslim are sacred to another Muslim.
