إِنَّآ أَرۡسَلۡنَا نُوحًا إِلَىٰ قَوۡمِهِۦٓ أَنۡ أَنذِرۡ قَوۡمَكَ مِن قَبۡلِ أَن يَأۡتِيَهُمۡ عَذَابٌ أَلِيمٞ١

innā arsalnā nūḥan ilā qawmihi an andhir qawmaka min qabli an yatiyahum ʿadhābun alīmun

Indeed, We sent Noah to his people, [saying], "Warn your people before there comes to them a painful punishment."
