"The Complete Siddur" (ha Siddûr ha šalem) is a standard Jewish prayerbook.

It includes the prayer yeqûm purqan, "May salvation arise".

According to the small explanatory footnote, provided in the above presented edition, the prayer was composed in Babylonia prior to the adoption by the Jews there of Arabic as their daily language - so certainly no later than the 800s. For the convenience of the reader I repeat the core of this footnote:

"... Yekum Purkan is not included in the Babylonian Siddurim of Amram Gaoo and Saadyah Gaon, but is mentioned in Mahzor Vitry which has come down to us from France.  refers to the heads of the semiannual conventions of the Babylonian scholars which were held during the months of Adar and Elul. The second Yekum Purkan, phrased like the first, is a prayer for the congregation, similar in content to the Hebrew paragraph , which singles out those who contribute toward the maintenance of the synagogue as well as to charity.

, the prayer in Aramaic, was composed in Babylonia where Aramaic remained the daily language for the Jews for more than a thousand years, until the ninth century when Arabic became the popular language. ..."
