﴿ بِسْمِ ٱللَّهِ ٱلرَّحْمَٰنِ ٱلرَّحِيمِ إِنَّآ أَرْسَلْنَا نُوحًا إِلَىٰ قَوْمِهِۦٓ أَنْ أَنذِرْ قَوْمَكَ مِن قَبْلِ أَن يَأْتِيَهُمْ عَذَابٌ أَلِيمٌۭ ﴾

“BEHOLD. We sent Noah unto his people. [saying:] "Warn thy people ere grievous suffering befall them!”

Verily We sent Noah to his people saying ‘Warn your people before there come on them — should they not believe — a painful chastisement’ in this world and in the Hereafter.
