Translation:

4. Say: "Do ye see what it is ye invoke besides Allah? Show me what it is they have created on earth or have they a share in the heavens? Bring me a Book (revealed) before this or any remnant of knowledge (ye may have) if ye are telling the truth!"

Notes (Tafseer)

4777. Some people may rush thoughtlessly into false worship, because it is the fashion or an ancestral custom, etc. They are asked to pause and see for themselves. Have the false gods or falsehood created anything? (They destroy much). Or have they any share or lot in the things we associate with the heavens,-spiritual well-being, etc.?

4778. 'Or is there any warrant for you from any earlier revelation, assuming that you do not believe in this Revelation? Or can you point to the least scrap or remnant of real knowledge on which you can base what We condemn as your false life?' No, you cannot.
