The Tur (O. Ch. 299 ) writes,"Some have the Minhag, on Motzei Shabbos,
to say all the Pesukim in Nach where, the name Eliyahu is mentioned.
They say it is a Segula against memory loss and to have Hatzlacha all week long."
Many people are familiar with the Motzei Shabbos Tefillah "Got fun Avraham".
Fewer people are aware of the Tefillah" Ribon Haolomim "(first part originates
from Yerushalmi).The Tur, Aruch Hashulchan and Mishna Verura all write to to
say it on Motzei Shabbos.
