Halakhah for Berakhot 21:3

The Sages ordained that three berakhot are recited together with the morning recitation of Shema, two berakhot before Shema and one after. They also ordained that four berakhot are recited along with the evening Shema – two before and two after (m. Berakhot 1:4). These berakhot complement and supplement the themes of the Shema, and they praise and thank God for creating and governing the world. Women are also exempt from reciting these berakhot, since they too are time-dependent: Birkhot Keri’at Shema of Shaḥarit can only be recited until the end of the first four hours of the day, and of Ma’ariv can be recited all night.
