They are not but [mere] names you have named them – you and your forefathers – for which Allah has sent down no authority. They follow not except assumption and what [their] souls desire, and there has already come to them from their Lord guidance.
1 Mufti Taqi Usmani
These are nothing but names you and your fathers have invented; Allah has sent down no authority attached to them. They are following nothing but conjecture and what their own souls desire, while guidance from their Lord has surely reached them.
