The lost generation

Just now I was reading this article from National Geographic about the "Lost fortresses of Sahara revealed". MasyaAllah, it reminds me of a number of verses in the Quran which speaks of generations destroyed. One close example to this article is found in Al Anaam.

"See they not, how many a generation We destroyed before them, whom We had established in the earth more firmly than We have established you, and We shed on them abundant showers from the sky, and made the rivers flow beneath them. Yet we destroyed them for their sins, and created after them another generation."
6:6 Al-Anaam (transliteration by Pickthall).

And even we, with our so called advancement in computers and technology, and sadly, evil too - who will save us from the wrath of Allah SWT, if He wants to destroy us?

Ya Allah, do guide us, and save us from your Torment. آمين
