Sayyiduna Abu Hurayrah (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "In Paradise there will be pillars of ruby, upon which there will be lofty chambers made of chrysolite (zabarjad). They will have open doors, and light will shine out of them like the light of a brilliant star." The narrator says: We submitted: O Messenger of Allah, who will dwell in them? The Prophet (peace and blessings be upon him) said: "Those who love one another for the sake of Allah Almighty, those who spend on one another for the sake of Allah Almighty, and those who meet one another for the sake of Allah Almighty (will dwell in them)."
Imam al-Bazzar recorded it; its chain contains a narrator, Muhammad bin Abi Humayd, and he is da'if (weak).
