Halakhah su Pe'ah 2:15

One must recite Birkhot Ha-Torah before studying any part of the Torah (SA 47:2). In other words, even one who only intends to learn Midrash or halakha on a particular day must recite Birkhot Ha-Torah at the onset of that day. The reason for this is that the entire Torah – whether the Written Torah or the Oral Torah, halakha and theology – was all given from God to Moshe at Sinai (y. Pe’ah 2:4), and when studying them, one must recite, “Who chose us from among all His nations and gave us His Torah.”
