That is a reference to the story of Noah, peace be upon him. Its position is elevated as a beginning, and the sentences that follow are news. That story is some of the unseen news revealed to you, unknown to you and your people before this, before My revealing it to you and informing you about it. Or before this knowledge that you acquired through revelation. Or before this time. So be patient in conveying the message and the harm from your people, just as Noah was patient and expected the outcome for you and for those who denied you, similar to what was destined for Noah and his people. Indeed, the outcome in victory and triumph belongs to the righteous. And His saying 'and not your people' means: your people, of whom you are one, despite their multitude and great number, if that is not their condition and they have not heard it or known it, then how about a man among them, as you say, who does not know this, Abdullah, nor the people of his town.
