Translation:

28. Why then was no help forthcoming to them from those whom they worshipped as gods besides Allah as a means of access (to Allah)? Nay they left them in the lurch: but that was their Falsehood and their invention.

Notes (Tafseer)

4808. The false things that they worshipped were figments of their imagination. If they had had any existence in fact, it was not of the kind they imagined.
