They nurtured what was there, helped it advance. Otherwise you'd have seen discoveries go down after the 7th Century instead of up.
That is definitely not true. Never in history were the Muslims of all the people know for nurturing and advancing the cause of science. Islam's history especially in India was one of he bloodiest anywhere in the world. Read
this. Within only a few centuries, Muslims barbarians decimated everything that took ages to build. Far form nurturing what was there, they deemd it Satanic and destroyed any thing that came their path. Under Islamic invasion India was back to stone age, humans were subjected to slaughter and genocide. After having been the worlds most advanced civilisation for millenias, India became a ravaged land laid waste by the maraudering Muslims. Whatever scientific, mathematical, technological, philosophical and spiritual advancement India made was under Hindu rule not Islam. Under Islam, India technologically regressed even behind Europe and eventually was defeated by the British mostly because of their superior technological prowess. Had the Muslims barbarians not come to rule over India perhaps India's history would have been very different.
That is definitely not true. Never in history were the Muslims of all the people know for nurturing and advancing the cause of science. Discoveries with Muslim names on them generally fall between the 8th and 13th Centuries. They conquered Persia in the mid 7th Century. They Also owned much of India by the 11th Century. Your timeline is off.
Even one of Islam's bloodiest conquerers in India, Mahmud, paid large amounts of gold as a patron of scholars during his invasion, while at the same time destroying temples and murdering infidels. Barbarians with a lust for knowledge, or at least the trappings of it. I still think they were trying to make up for being a backwater culture.

A lot of history would have been different if not for religious wars and persecution.
