9. Quran verse and the related information:

السلام عليكم ورحمة الله وبركاتة

بِسْمِ ٱللَّٰهِ ٱلرَّحْمَٰنِٱلرَّحِيمِ

 

وَكَمْ أَهْلَكْنَا مِنَ ٱلْقُرُونِ مِنۢ بَعْدِ نُوحٍۢ ۗ وَكَفَىٰ بِرَبِّكَ بِذُنُوبِ عِبَادِهِۦ خَبِيرًۢا  بَصِيرًۭا                                                   

Imagine˺ how many peoples We have destroyed after Noah! And sufficient is your Lord as All-Aware and All-Seeing of the sins of His servants.    

Warning the disbelievers of the Quraysh for rejecting His Messenger Muhammad ﷺ, Allah says that He destroyed other nations who rejected the Messengers after Nuh. This indicates that during the centuries between Adam and Nuh, humans were following Islam, as Ibn `Abbas said: "Between Adam and Nuh there were ten generations, during all of which humans were following Islam." The meaning (of the Ayah) is: "You disbelievers are not more dear to Allah than they were, and you have rejected the most noble of the Messengers and the best of creation, so you are more deserving of punishment."
