Mr K2a your madrassa education is wrong on my levels.
Let's see if Muzlimz actually gave us ALL these things *cough apart from terrørism cough*.

1. Algebra.
Arabic scholars TRANSLATED Vedic knowledge, they didn't invent Algebra.
Read it carefully 👇🏻

2. Surgery.
- Sushruta is known as the father of surgery.
- Sushruta Samhita is considered as the oldest text about surgery. It is an ancient Sanskrit text on medicine and surgery, and one of the most important such treatises on this subject to survive from the ancient world.+
+ Muslims consider Al-Zahrawi as the father of surgery for his surgical text Kitab al-Tasrif (a cutting-edge compendium on every known practice & procedure) BUT Sushruta Samhita which has knowledge about almost all types of Surgery, Ayurveda, Medicine, instruments & procedures+
was written before Al-Zahrawi was born.
( Al-Zahrawi was born in 936 AD while Sushruta was born in 800 AD & Sushruta Samhita is dated to 878 AD ).
3. Flying Machine.
Yes, it's true that Abbas ibn Firnas (809-887 AD) designed the first human-carrying glider but there are mentions of Vimāna in scriptures such as Vedas, Ramayana, etc. (were written before the birth of Prophet Muhammad)
Even Jain texts have mention of Vimanas.
4. University
Lol, ever heard of Nalanda ancient university & Takshila university?
Al-Quaraouiyine is considered as oldest STILL OPERATING university, not THE OLDEST university.
It was founded in 859 AD.
Nalanda ancient university was founded in 500 AD by King Kumaragupta 1. +
Nalanda was destroyed three times but was rebuilt only twice. It was ransacked and destroyed by an army of the Mamluk Dynasty of the Delhi Sultanate under Bakhtiyar Khalji in c. 1200 CE.
5. Hospital.
Muslims consider the oldest hospital to be the one which was built in Baghdad in 805 AD BUT
The Mihintale hospital (the remains of which are there in Sri Lanka) was built in 3rd century AD.
6. Optics.
Around 700BC ancient Egyptians and Mesopotamians started polishing crystals (often quartz) in an attempt to replicate optical abilities that they noticed can be made with water. One of the most famous examples of those original lenses is the Nimrud lens.+
Created in ancient Assyria between 750 and 710 BC, this lens was used as a decorative piece, magnifying glass or tool for starting fires. First steps in optics that were made in Africa and the Middle East only fueled imagination and resolve of the Greek and Roman mathematicians+
physicist and inventors whose experiments formed the basis of the classical optics. Three most popular school of thought regarding optics in that time were “emission theory” formed by Plato, “intromission theory” that was supported+
Democritus, Epicurus, Aristotle, add the “geometrical optics” that was created by Euclid several hundred years after Plato. All these theories sadly almost disappeared from the scientific circles in Europe after the fall of the Roman Empire.
7. Music.
Greek, Egyptian, Indian and other civilizations did have musical instruments before the 7th century.

And, isn't music haram in Islam?
8. Coffee.
It has no concrete evidence but yes, it is believed that a 9th-century Ethiopian goat-herder named Kaldi/Khalid discovered the coffee beans.
Allegedly, Kaldi observed his goats behaving erratically after eating the red berries from a nearby Coffea arabica tree.+
He tried some of them himself and was soon acting as hyper as his herd. He then brought a batch to a monastery where they were derided for their stimulating effects during long hours of prayer. The religious leaders there threw the tree’s beans onto a fire to destroy them but+
the pleasing aroma of the roasted beans convinced them to give the coffee a second chance. Much like with tea, they put the roasted beans into warm water & the beverage was born.
Despite the legend, it’s thought that the practice of chewing coffee beans as a stimulant was around+
for centuries before Kaldi's alleged discovery. People would grind the beans to mix with butter & animal fat to preserve & eat on long journeys. Similarly, Sudanese slaves are thought to have chewed on coffee beans to help them survive their difficult voyages on trade routes.
9. Crankshaft
In 1206, Al-Jazari invented an early crankshaft, which he incorporated with a crank-connecting rod mechanism in his twin-cylinder pump. Like the modern crankshaft, Al-Jazari's mechanism consisted of a wheel setting several crank pins into motion, +
with the wheel's motion being circular and the pins moving back-and-forth in a straight line.
The crankshaft described by al-Jazari transforms continuous rotary motion into a linear reciprocating motion & is central to modern machinery such as steam engine, internal combustion+
engine & automatic controls. He used the crankshaft with a connecting rod in two of his water-raising machines: the crank-driven saqiya chain pump and the double-action reciprocating piston suction pump. His water pump also employed the first known crank-slider mechanism.
BUT The earliest evidence for a crank and connecting rod in a machine appears in the late Roman Hierapolis sawmill from the 3rd century AD and two Roman stone sawmills at Gerasa, Roman Syria, and Ephesus, Asia Minor (both 6th century AD).
10. Toothbrush.
Neem twigs were used as a toothbrush in ancient India. The edge of the twig was chewed to form bristles that cleaned the teeth. The practice of oral hygiene included chewing on the twig until it developed bristles & then it was used to brush the teeth.
In China in 1498, coarse boar hairs were attached to handles made of bamboo or bone.
A frayed twig was developed by the Babylonians and the Egyptians in 3000 BCE (other sources have found that around 1600 BCE).
The first toothbrush of a more modern design was made by William Addis in England around 1780 – the handle was carved from cattle bone and the brush portion was still made from swine bristles. In 1844, the first 3-row bristle brush was designed.
In 1938, nylon bristles were introduced by the company Dupont de Nemours. The first nylon toothbrush was called Doctor West's Miracle Toothbrush.
12. Camera
- Johann Zahn, seventeenth-century German author of Oculus Artificialis Teledioptricus Sive Telescopium.

- Joseph Nicéphore Niépce, a French inventor, usually credited as the inventor of photography and a pioneer in that field.

13. World map.
Anaximander, a Greek philosopher. Lived in Miletus, Ionia. He belonged to the Milesian school & learned the teachings of his master Thales.
He succeeded Thales & became the second master where he counted Anaximenes & arguably, Pythagoras amongst his pupils.
14. Surgical instruments.
There is knowledge about surgical instruments in Sushruta Samhita which was written before before Al Zahrawi (father of surgery according to Muslims) was even born.
15. Bath & Wash
Yes there was no water before 7th century AD🥴🤦🏻‍♀️

- Earliest recorded evidence of soap-like materials dates back to around 2800 BC in ancient Babylon. Formula for soap consisting of water, alkali & cassia oil was written on a Babylonian clay tablet around 2200 BC.
16. Windmill
The earliest known wind powered grain mills & water pumps were used by Persians in A.D. 500 & by the Chinese in A.D. 1200.
First windmill manufactured in the U.S. was designed by Daniel Halladay, who began inventing windmills in 1854 in his Connecticut machine shop.
17. Inoculation
It riginated as a method for prevention of smallpox by deliberate introduction of material from smallpox pustules into the skin. This generally produced a less severe infection than naturally acquired smallpox, but still induced immunity to it.+
This first method for smallpox prevention, smallpox inoculation, is now also known as variolation. Inoculation has ancient origins and the technique was known in India, Africa and China.

Indians knew smallpox inoculation before Edward Jenner invented the vaccine.+
18. Weaving.
Bruh Seriously?
Weaving was practiced even before
Jesus Christ was born.
And, The Islamic geometric patterns were derived from simpler designs used in earlier cultures: Greek, Roman and Sasanian.
19. Astronomy.
This topic doesn't need much discussion. Just google about Indian Astronomy and Astronomy in Hinduism.
And Greek astronomy is also interesting.
20. Gardens
Yes there were no Gardens before Islam. It was all barren desert land.
Smh.
21. Distillation
Early evidence of distillation was found related to alchemists working in Alexandria in Roman Egypt in the 1st century. Distilled water has been in use since at least c. 200, when Alexander of Aphrodisias described the process.
22. Quilting
In 1924 archaeologists discovered a quilted floor covering in Mongolia, estimated to date between 100 BC and 200 AD.
23. Chess
Oh bhai maaro mujhe maaro! 😭
At least you should have googled once about the history & origin of Chess.
Chess was invented in India by Hindu Kings!
