Another possible excuse from them was to say:

أَوْ تَقُولُوا إِنَّمَا أَشْرَ‌كَ آبَاؤُنَا مِن قَبْلُ وَكُنَّا ذُرِّ‌يَّةً مِّن بَعْدِهِمْ ۖ أَفَتُهْلِكُنَا بِمَا فَعَلَ الْمُبْطِلُونَ ﴿173﴾

"Or you should say, "It was our forefathers who associated partners with Allah and we were (only) a progeny after them. So, would you destroy us on account of what the false ones did?"

The verse precludes them from seeking refuge in saying that they were unaware of the Truth. Being a progeny of their forefathers they only followed their path. Therefore they should not be punished for the error of their forefathers. The verse has said that they shall not be punished for the acts of their forefather. It was their own fault and their apathetic attitude that led them to this disaster. It is because the covenant had sown the seed of Truth in their heart and it was not difficult for them to decide that the stones, shaped by themselves into idols, or the fire, the trees and other created beings could, in no way, be considered as being their creator or possessing powers of helping them in their need.
