﴿ ۞ كَذَّبَتْ قَبْلَهُمْ قَوْمُ نُوحٍۢ فَكَذَّبُوا۟ عَبْدَنَا وَقَالُوا۟ مَجْنُونٌۭ وَٱزْدُجِرَ ﴾

“[LONG] BEFORE those [who now deny resurrec­tion] did Noah’s people call it a lie; and they gave the lie to Our servant and said, “Mad is he!” - and he was repulsed.”

The people of Noah denied kadhdhabat has feminine inflection on account of the import referring to a feminine noun qawm ‘tribe’ before them before Quraysh. Thus they denied Our servant Noah and said ‘A madman!’ and he was reviled they repulsed him with insults and in other ways.
