It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Do not sever relations, do not harbor hatred, do not turn your backs on each other, and do not be jealous of one another. And O servants of Allah! Be brothers to one another. And it is not permissible for any Muslim to cut off speech with his brother for more than three days.
