Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: "Indeed, Allah Almighty will have special companions on the Day of Resurrection on the right side of the Throne, and both of Allah's Hands are right, upon pulpits of light; their faces will be of light. They will be neither prophets, nor martyrs, nor the truthful ones (siddiqin)." It was asked: O Messenger of Allah, who will they be? He (peace and blessings be upon him) said: "Those who loved one another for the majesty of Allah Almighty."
