הלכה על ברכות 8:6

Although the recitation of Shema and its berakhot and the recitation of the Amida are two separate mitzvot, a woman who recites them both must adjoin them; immediately upon finishing Ga’al Yisrael she must begin the Amida. The Sages state that anyone who adjoins redemption to prayer indeed merits life in the next world (Berakhot 4b). If one adjoins them while praying ke-vatikin (at hanetz ha-ḥama), he is promised that he will not be harmed that whole day (Berakhot 9b and Tosafot ad loc.). One who interrupts between redemption and prayer is like a king’s confidant who comes and knocks on the king’s door, and when the king emerges to find out what he wants, the confidant leaves to take care of another matter, which then results in the king’s withdrawal from him.
