Responsa for Shabbat 47:1
תניא כוותיה דרב חסדא כל אלו שאמרו אין מדליקין בהן בשבת מדליקין בהן ביום טוב חוץ משמן שריפה לפי שאין שורפין קדשים ביום טוב:

Hisda: All those [materials] concerning which the Rabbis ruled, One must not light therewith on Sabbath, may be used for lighting on Festivals, except oil of burning,<span class="x" onmousemove="('comment',' [Although one may light therewith on Sabbaths, one may not do so on Festivals, v. Tosaf a.l.]. ');"><sup>1</sup></span> because sacred food must not be burnt on Festivals. The scholars propounded: Is Hanukkah to be mentioned in grace after meals? Since it is a Rabbinical [institution], we do not mention it; or perhaps it is mentioned to give publicity to the miracle? — Said Raba in R. Sehora's name in R. Huna's name: It need not be mentioned; yet if one comes to mention it, he does so in the 'Thanks' [benediction].<span class="x" onmousemove="('comment',' The second benediction of grace; so called because it commences with, 'we give thanks unto Thee'. ');"><sup>2</sup></span> R. Huna b. Judah chanced to visit Raba's academy [and] thought to mention it [Hanukkah] in [the benediction] 'he will rebuild Jerusalem.'<span class="x" onmousemove="('comment',' The fourth benediction of grace. ');"><sup>3</sup></span>
