Among his later descendants was Moses ben Naḥman (Naḥmanides); Judah Albargeloni is said to have been Isaac's pupil.
He was one of five prominent contemporaneous scholars named Isaac and the regard in which he was held by his own and succeeding generations is indicated by the fact that he is simply designated "Ha-Rab Albargeloni."
Noteworthy among his liturgical poems are his Azharot, included in the rituals of Constantine, Tlemçen, Tunis, Morocco, Algeria, and Oran.
Al-Ḥarizi remarked: "He has put the religious laws into rime, and has fitted them so well to Biblical passages that it almost seems as if the work had been inspired by a higher power."
Isaac faithfully copied the division of the laws and interdictions of the Halakot Gedolot; at times even following its wording, while he also took into account the regulations of traditional literature referring to Biblical prescriptions.
