There was no golden age of Islam. Any and all 'inventions' ascribed to 'Moslems' were the work of Jews, Christians, Berbers, Persians or Hindus, with Islamified names. One such 'genius' was Al Kindi. He was a Christian Arab who was a 'sage' at the Caliphate court in Baghdad some 1200 years ago. Far from being a 'Moslem', Kindi was critic of the moon cult of Mecca and satirized the nonsense that is the Koran with penetrating analysis.
Kindi's work was so damaging to Islam, that anyone found with copies of his critiques would have their house razed to the ground. But remember – Islam is tolerance, love and inquiry. So the huge brains and multiculti loving nitwits tell us. It should be pointed out that Kindi did not invent, innovate, or improve. Like most Arabs he simply accepted Greek theology [see here]. His main contribution was to drive a stake into the heart of Islamic theology by mocking the Koran's illiteracy and obvious mendacity. This is why Moslems were forbidden to read his work....
“One of the most compelling debates that emerged from this short breath of oxygen was a dialogue between the Arab Christian Abd al-Masih Al Kindi, a member of the Caliphate court, and the Muslim Abd-Allah al-Hashimy (both pseudonyms). This exchange was known as the Apology (risala) of Al Kindi. An abridged English translation was produced by the Scottish Orientalist Sir William Muir in 1887. (See: http://www3.nd.edu/~reynolds/nehc20624/al-kindi.pdf)
After the suppression of the rational Mu’tazilites, copies of this debate continued to circulate in the Middle East. The religious leaders were so alarmed by the devastating effect the arguments were having on Muslims, a law was promulgated in Egypt that anyone found with a copy of the document would have his house razed to the ground, and his neighbors in the nearest forty houses would also have their houses destroyed. That is the equivalent of having an entire city block leveled for possessing a single forbidden document! (See: Robert R. Reilly, The Closing of the Muslim Mind, 2010, page 36.)
So what were the dozen most glaring absurdities Al Kindi found in Islam that caused the Islamic religious authorities to become so alarmed?
No evidence of God’s help to Muslims..
Muhammad’s commands to assassinate his critics and to steal the property of the innocent Banu Qaynuqa were clearly evil..
Muhammad’s acknowledged preference for sweet scents and women was unbecoming of a prophet ..Al Kindi points out that Muhammad had fifteen wives and two slave girls, and he questions how Muhammad could have possibly treated them all with equality per Surah 4:4.
Muhammad failed to meet the two tests of prophesy – revelation of the past and revelation of the future. ..
Muhammad could not perform miracles as Jesus did..
The apostasy of most Muslims after Muhammad’s death (i.e., The Wars of Ridda – 632-633) showed that Muslims had converted outwardly but not inwardly by faith...
The Quran was not only the work of many different hands, but it was unremarkable both in its content and its eloquence..
Islam was propagated by material and sensual inducements rather than by faith or peace with God — The allure of Paradise..
The Hajj rites are pagan rituals handed down from the Sun-worshippers and the Brahmas..
There was and is plenty more one could find to criticize Muhammadism.
Kindi asks Moslems a most profound and perplexing question:
“What sense is there in the washing of your hands and feet while your hearts are set upon bloodshed, and rapine, and the enslaving of women taken in war?”
Kindi adjured his Moslem friends to leave the darkness of the Muhammadan cult and avail themselves of the truth of Christianity and the Gospel. Nothing has changed with Islam or its fascistic paganism, since the time of Kindi.
