ALLAH THE LIGHT OF HEAVEN AND THE EARTH

My father - Allah be pleased with him - narrated to us, he said: Sa`d b. `Abdullah narrated to us, from Ya'qoub b. Yazeed, from `Abbas b. Hilal who said:
I asked (Imam) al-Ridha [a] about the saying of Allah, Mighty and Exalted, "Allah is the light of the heavens and the earth" [24:35]

He replied: (He is the) Guide for the people of the heaven, and (He is the) guide for the people of earth.

And in the narration of al-Barqiy: "(He has) Guided those in the heavens, and (He has) guided those on earth."
