Musannaf Ibn Abi Shayba 33:830

Narrated to us Abd al-Rahman ibn Muhammad al-Muharibi, from al-Ifriqi, from Abu Alqama, from Abu Hurayrah, who said: "Indeed, the inhabitants of the heaven see the houses of the people of dhikr (remembrance of Allah) shining for them just as the stars shine for the inhabitants of the earth."
