Daniel al-Kumisi (? in Damagan, Tabaristan – 946, in Jerusalem) was one of the most prominent early scholars of Karaite Judaism. He flourished at the end of the ninth or at the beginning of the tenth century. He was a native of Damagan, the capital of the province of Qumis, in the former state of Tabaristan, (present-day Semnan province of Iran), as is shown by his two surnames, the latter of which is found only in Qirqisani. His attitude to Anan ben David and his violent opposition to the Ananites (i.e., the first Karaites, Anan's followers and immediate successors) are characteristic of his place in Karaism. At first he esteemed Anan highly, calling him rosh hamaskilim ("chief of the scholars"); but later he despised him and called him rosh ha-kesilim ("chief of the fools"). Nevertheless, Daniel's opinions were respected by the Karaites.
Daniel later immigrated to Jerusalem, and founded the order of the "Mourners of Zion." He may have built the oldest Karaite Synagogue, which is located in Jerusalem. Espousing proto-Zionist views, he urged his fellow Karaites to return to Israel, and called those who opposed doing so "fools who draw the Lord's wrath" in his Epistle to the Diaspora.
As regards Daniel's theories, he denied that speculation could be regarded as a source of knowledge, and, probably in accordance with this tenet, he maintained, in opposition to Anan, the principle that the Biblical laws must not be interpreted allegorically, nor explained contrary to the simple text (see below). He evinces little regard for science, as, for instance, when he asserts that it is forbidden to determine the beginning of the new moon by calculation, after the manner of the Rabbis, because such calculations are condemned like astrology, and the practise of them is threatened with severe punishment, according to Isaiah xlvii. 13–14. Yet Daniel himself, in his commentary to Leviticus xxvi., indulges in long reflections on the theodicy and on the suffering of the pious. His conception of the angels, also, is most extraordinary. He says that wherever "mal'akhim" (angels) are mentioned in the Bible, the designation does not refer to living, speaking beings who act as messengers, but to forces of nature, as fire, fog, winds, etc., by means of which God performs His works (compare Maimonides, "Moreh," ii. 6). This may be due to the influence of the Sadducees (who also denied the existence of angels; compare Acts xxiii. 8), as works circulated among the earlier Karaites named after Zadok and containing Sadducee opinions.
Legal Decisions
Daniel favored a rigorous interpretation of the Torah. The following decisions of his have been preserved: It is forbidden to do any work whatever on the Shabbat (Sabbath)—even to clean the hands with powder—or to have any work done on the Sabbath by a non-Jew, whether gratuitously, or for wages or any other compensation. The burning of lights is forbidden not only on Friday evenings, but also on the evenings of the festivals. In the description in Lev. xxiii. 40 of the trees which, according to Daniel, were used in erecting the sukkah, the phrase "periez hadar" (the fruit of goodly trees) is more definitely explained by "kappot temarim" (branches of palms), the palm being distinguished for its beauty (Cant. vii. 8).
