Musannaf Ibn Abi Shaybah 36810 — Reports on the description

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Those who love one another for the sake of Allah will be on the Day of Resurrection on a pillar of red ruby. At the top of the pillar there will be seventy thousand rooms. They will look down upon the people of Paradise, and when one of them looks down, his beauty will fill the homes of the people of Paradise, just as the light of the sun fills the homes of the people of this world. Then the people of Paradise will say: 'Take us out to those who love one another for the sake of Allah.' Then they will go out and look at their faces, which will be like the moon on the night of the full moon. They will be wearing green garments, and on their faces will be written: 'These are the ones who loved one another for the sake of Allah.'"
