Kirimi was the author of Sefat Emet (not to be confused with the book of the same name by Rabbi Yehudah Aryeh Leib Alter (1847-1905) of Gora Kalwaria, Poland), a commentary on the Pentateuch, in which he tries to refute the interpretations of the Karaites when they are in contradiction to those of the Rabbinites. Kirimi says in the preface that he wrote the work at the request of many notable Jews and especially of his Karaite pupil Hezekiah b. Elhanan ha-Nasi, whom he held in high esteem.
A part of the preface is in verse, the last two lines of which may be translated:
To the one who asks for the author's name, answer: Abraham who was born at Kirim. His date is 5118 (1358).
