רב שר שלום גאון

Rav Sar Shalom Gaon was one of the Geonim, the heads of the great Babylonian academies whose rulings shaped Jewish law in the centuries after the close of the Talmud. He is brought in later halachic literature as an early authority whose decisions and customs guided practice in matters of marriage and daily prayer.

In the supplied material his name surfaces within discussions clustered in Orach Chaim and Even HaEzer — the laws of the ketubah and the requirement that a husband write a proper document for his wife, alongside many topics of tefillah: the order of the evening, afternoon, and festival prayers, the special insertions on public fast days and the High Holy Days, the laws of reading the Torah and maintaining silence before the open scroll, and the customs surrounding the Seder cups and Hallel. These passages place him among the early authorities whose practice the Rishonim weighed and recorded as they fixed the settled halachah.
