[Noah] said, 'And what knowledge have I of what they used to do?' meaning: of what they practice. I only accept from them their outward appearance, and I have no knowledge of the hidden state of their affairs.
﴿قَالَ وَمَا عِلْمِي بِمَا كَانُوا يعْملُونَ﴾ أَيْ: بِمَا يَعْمَلُونَ، إِنَّمَا نَقْبَلُ مِنْهُمُ الظَّاهِرَ، وَلَيْسَ لِي بِبَاطِنِ أَمرهم علم.
