That is all lies.
Jordan existed as far back as the 7th century, continuously.
{...
In the early 7th century, the area of modern Jordan became integrated into the new Arab-Islamic
Umayyad Empire (the first Muslim dynasty), which ruled much of the Middle East from 661 until 750 CE. At the time, Amman, today the capital of the Kingdom of Jordan, became a major town in "Jund Dimashq" (the military district of
Damascus) and became the seat of the provincial governor. In fact, the name "Al-Urdun" (Jordan) was used on Umayyad post-reform copper coins beginning in the early 8th century and represent the earliest official usage of the name adopted in the 20th century for the modern state. Additionally, lead seals with the Arabic phrase "Halahil Ardth Al-Urdun" (Master of the Land of Jordan), dating from the late 7th to early 8th century CE, have been found in Jordan as well. Additionally, Arab-Byzantine "Standing Caliph" coins minted under the Umayyads also have been found bearing the mint-mark of "Amman". Thus, usage of the names Al-Urdun/Jordan and Amman date back to at least the early decades of the
Arab-Muslim takeover of the region.

Under the Umayyad's successors, the
Abbasids (750–1258), Jordan was neglected and began to languish due to the geopolitical shift that occurred when the Abassids moved their capital from Damascus to
Kufa and later to
Baghdad.
After the decline of the Abbasids, parts of Jordan were ruled by various powers and empires including the
Crusaders, the
Ayyubids, the
Mamluks as well as the
Ottomans, who captured most of the
Arab world around 1517. ...}
Both Palestine and Jordan together were known as Trans Jordan around WWI, but the Allies split them up, to ensure no Jewish immigration was allowed to Jordan.
No Jews were ever "ethnically cleansed" from any Arab country ever.
It would be against the Moslem Quran, which specifically says Jews are to be protected by Moslems, as "Brothers of the Book", referring to the Old Testament.
