"Pharaoh said: Ye believe in Him before I give you leave! Lo! this is the plot that ye have plotted in the city that ye may drive its people hence. But ye shall come to know! 124 Surely I shall have your hands and feet cut off upon alternate sides. Then I shall crucify you every one," (Quran 7:123-124).
When was crucifixion invented?
One source cites Encyclopaedia Britannica as saying the first report of crucifixion is around 520-19 during Darius I of Persia's reign.
Britannica reports that the first historical record of Crucifixion was about 519 BC when "Darius I, king of Persia, crucified 3,000 political opponents in Babylon" (Encyclopaedia Britannica, crucifixion)

NOTE however that this first report comes nearly a millenium after the alleged Qur'anic incident involving Pharoah of Egypt during Moses' lifetime.
"an important method of capital punishment, particularly among the Persians, Seleucids, Carthaginians, and Romans from about the 6th century BC to the 4th century AD. Constantine the Great, the first Christian emperor, abolished it in the Roman Empire in AD 337, out of veneration for Jesus Christ, the most famous victim of crucifixion."

We have no record that Egyptians used crucifixion as punishment in the time of Moses (1450 BC, conservative date; 1200 BC at the latest) or even Joseph (1880 BC, conservative date). Crucifixion only becomes a punishment much later in history and then first in another culture before it has been taken over by the Egyptians. Such threats by a Pharaoh at these times are historically inaccurate but for some reason they are in the Quran.
