Halakhah su I Samuele 2:37

2. We take out two Torah scrolls. In the first one, we read five portions from "God attended Sarah" [Genesis 21:1] until "After these things" [Genesis 22:1]. If it is Shabbat, we read seven portions [from this selection]. The maftir reads from the second scroll from Pinchas, "In the seventh month..." [Numbers 29:1] and for the haftarah, "There was a man from Ramatayim" [1 Samuel 1:1] until "He will bring triumph to His annointed one" [1 Samuel 2:10]. Rem"a: Some places have the custom of calling up the shofar blower for one of the five aliyot to the Torah (Kol Bo).
