Al-Ma'idah 5:104

Wa-itha qeela lahum taAAalawila ma anzala Allahu wa-ila arrasooliqaloo hasbuna ma wajadnaAAalayhi abaana awa law kana abaohumla yaAAlamoona shay-an wala yahtadoon

And when it is said to them, "Come to what Allāh has revealed and to the Messenger," they say, "Sufficient for us is that upon which we found our fathers." Even though their fathers knew nothing, nor were they guided?

When it is said to them, “Come to what Allah has sent down, and to the Messenger;” they say, “Sufficient for us is that on which we have found our forefathers.” Is it so, even though their forefathers knew nothing, and had no guidance either?
