وَأُوحِىَ إِلَىٰ نُوحٍ أَنَّهُۥ لَن يُؤْمِنَ مِن قَوْمِكَ إِلَّا مَن قَدْ ءَامَنَ فَلَا تَبْتَئِسْ بِمَا كَانُوا۟ يَفْعَلُونَ Qur’an Hud (11:36)Waoohiya ila noohin annahu lan yumina min qawmika illa man qad amana fala tabtais bima kanoo yafAAaloona
The story of Noah is resumed. A point was reached, when it was clear that there was no hope of saving the sinners, who were courting their own destruction. It was to be a great Flood. So Noah was ordered to construct a great Ark or Ship, a heavy vessel to remain afloat in the Flood, so that the righteous could be saved in it.
