The tafsir of this ayah is mentioned in
Nuh 71:4 ⧉
Noah is perhaps the first prophet after Adam. The message that he gave to the corrupted people of those days has been put here in three words—worship (‘ibadah), fear of God (taqwa) and obedience to the Prophet (ita‘ah), i.e. the worshipping of God and renouncing the worship of anything other than God, leading one’s life in the world with the fear of God in one’s heart and considering the prophet of God an example to be followed in all matters. This has been the real message of all prophets in every age and this is the true message of the Quran itself.
