It is narrated from Sayyiduna Hisham bin Amir al-Ansari (may Allah be pleased with him) that I heard the Messenger of Allah (peace and blessings be upon him) saying: "It is not lawful for a Muslim to cut off relations with a fellow Muslim for more than three days. As long as the two of them persist in this estrangement, both of them are deviating from the path of truth. Whichever of the two takes the lead in returning to make peace, his being first to return will be an expiation (of sins) for him. If he greets the other with salam but the other does not accept his greeting, the angels will return the greeting of the one who greeted, while the devil will respond to the other (the one who rejected the greeting). And if the two of them die in this state of estrangement, they will not enter Paradise, or (he (peace and blessings be upon him) said:) they will never be together in Paradise."
