The Revelation to Nuh concerning what would happen to the People and the Command to prepare for It Allah, the Exalted says; وَأُوحِيَ إِلَى نُوحٍAnd it was revealed to Nuh:Allah, the Exalted, sent revelation to Nuh when his people hastened the vengeance and punishment of Allah upon themselves. Then, Nuh supplicated against them, as Allah mentioned, when He said;رَّبِّ لَا تَذَرْ عَلَى الاٌّرْضِ مِنَ الْكَـفِرِينَ دَيَّاراًMy Lord! Leave not one of the disbelievers inhabiting the earth! (71:26)And he said,فَدَعَا رَبَّهُ أَنُّى مَغْلُوبٌ فَانتَصِرْThen he invoked his Lord (saying):"I have been overcome, so help (me)!" (54:10)At this point Allah revealed to him,أَنَّهُ لَن يُوْمِنَ مِن قَوْمِكَ إِلاَّ مَن قَدْ امَنَ"None of your people will believe except those who have believed already.فَلَ تَبْتَيِسْ بِمَا كَانُواْ يَفْعَلُونَSo be not sad because of what they used to do." Therefore, do not grieve over them and do not be concerned with their affair
