Just a piece of advice. Refrain from quoting the Qur'an to make discussion points if you don't understand the arabic of the Qur'an.Do you even understand what such a golden age would require?
To have such a golden age would require science to flourish, and science does not always conform to Islamic dogma, as seen jf. Quran 86: 5-6.
It would also mean debate about the ideal form of government and even what the basis of government should be based on either empirical evidence and/or logical deductions, thereby questioning Sharia.
This is very unlikely to happen in pseudo theocracy that does not accept diversity of thought and dissent.
Also, these specific verses have bodies of work dedicated to them describing the accuracy of these statements.
