Then they rejected him, so We saved him and those with him in the ark and made them successors, and We drowned those who were rejecting Our verses. Then you see how was the consequence of those who were warned.
The first Messenger deputed by Lord was Nooh, and he was deputed with the Message Adhikr as explained in verse 4: 163. Even though he reminded his people for about 950 years, a few of them only believed as told in verses 29: 14-16. Most of his people rejected Adhikr and followed the hypocritical transgressors whose wealth and children increased them nothing except loss. Thus, they became wrongdoers. Then Lord inspired Noah to pray as: “Oh My Lord! Don’t spare upon the earth anyone from the disbelievers; indeed, if You spare them, they will mislead Your servants and will not deliver anyone except Fujjar and Kuffar, and you don’t increase for these wrongdoers anything except destruction” as told in verses 71: 21-28. Thus, Lord drowned wrongdoers and saved Nooh and believers with him in an ark as explained in verses 11: 25-49. If a people of Messenger become wrongdoers, transgressors, and Mujirims after they had been warned with Adhikr, they will be destroyed as explained in verses 7: 73-79.
Today, there is no group of believers anywhere in the world. So, the odd-believer is commanded not to seek forgiveness for the hypocritical transgressors and Kuffar as explained in verses 9: 84-85. Instead, he is commanded to do Jihad with Adhikr against them as explained in verse 9: 73. See the explanations 3: 10; 6: 133 and 9: 67-68.
