Rav Shmuel was ordained as Nagid in the year 4787 from the son of King Habbus, and he did good for Israel in Spain and the lands of the West and Africa and the land of Egypt and in Ascalon and up to the yeshiva of Babylon and up to the holy city. All the people of his generation in these lands, he would support them from his wealth and acquired many books and the Holy Scriptures and the Mishnah and the Talmud, and whoever wanted his Torah to be his trade in all the land of Spain and in these lands he would support him.

And he revived many sages who would have perished in poverty. And he wrote books: Mavo HaTalmud, and Sefer HaOsher, and Hilchot HaNagid on the laws of blessings, and composed much poetry both sacred and secular. This man would fight in the king's battles and conquer cities and lands, and in his palace he engaged in Torah and wisdom and doing kindness. He was Nagid for about thirty-five years [(Shalshelet HaKabbalah, letter 39, part 2)] and died around year 4818.

He is buried in Granada [(Gedolei Yisrael)].
