The Thunder - 13:16
"Say: "Who is the Lord of the heavens and the earth?"Say: "Allah."Say: "Have you taken as saints besides Him those who can neither benefit nor harm even themselves?"Say: "Are the blind and the seeing alike, or the darkness and the light alike?"Or have they found partners who create as Allah has created, and have they confused their creations with each other? Say: "Allah is the Creator of all things, He is One, Sovereign."
