It is narrated from Sayyiduna al-Irbad bin Sariyah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Allah Almighty says: "Those who love one another for the sake of My majesty (greatness) will be in the shade of My Throne on the Day when there is no shade but My shade."
