It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: The upper chambers of Paradise for those who love each other for the sake of Allah will appear as a shining star rising in the east or west. It will be asked: Who are these people? It will be answered: These are those who love each other for the sake of Allah's pleasure.
