The Prophet peace be upon him and his progeny, said: "Those who befriend each other for the sake of Allah, Most High, shall be resting on the pillars of ruby in the Paradise, supervising the inmates of Paradise. Whenever one of them comes forth, his splendour shall fill the houses of the people of Paradise. Then the people of the Paradise shall say: ’Let us out so that we can have a glimpse of those who befriended each other for the pleasure of Allah.’ He said: "Then they will be brought out to see them. One of them will have a face like the full moon, and on their foreheads will be written: These are the people befriending each other for the sake of Allah!"
