Al-A'raf · 7:173

173. 'Lest you might say that your ancestors were the ones who broke the promise, taking others as partners with Allah, and that you were just following them. In this way, you would say: 'O our Lord! Will You destroy us for what our ancestors did, making our actions worthless because of taking others as partners with You?! Indeed we carry no sin because we were just following our ancestors and had no knowledge.'
