Some Muslims were very creative in the architecture for their mosques and the very artistic tiles they designed and fired for them. Muslims also had a hand in making the Damascus steel used in their superior swords during the Crusades. The other "Islamic sciences" has been debunked. They appropriated from superior cultures in India and Persia.
Muslims were not scientists and the Egyptian Pyramids were not designed/engineered/built by blacks as some Afro-centric charlatans like to teach in America
You will not convince any one any thing. There are many here are so insecure about their own beliefs they tirelessly look under rocks to find fragments that might undermine their beliefs.
As with the Obama administration, Facts are irrelevant
Even their architecture was taken from other more-advanced pre-Islamic societies in the Middle East. Don’t forget that these were cultures that had produced things such as the Hanging Gardens of Babylon (which were long gone by the rise of Islam, although Baghdad, Syria and Persia still had beautiful buildings and urban centers).
Mohammed’s Arabs had virtually nothing prior to their rampage. They were tent-dwelling nomads, and everything they appropriated, even in the middle east, was produced prior to the rise of Islam. The conquest varied only in how long it took the Muslims to destroy these other cultures and reject the things they initially seized from them.
Even “Damascus” steel is actually Wootz steel, from southern India.

“Islamic” architecture, like all those Iranian mosques, isn’t really as Islamic as one would want to believe. Such wonders of architecture are largely from regions east of Iraq, which the invading Muslims assumed for themselves.
Arabia, for example, has very little significant architecture of the category. Even the Turks took it from the Persians. It would be safe to assume that the architecture developed in Persia long before it was infested by Islam.
