1. The Laws Governing the Shabbos Afternoon Service, 2 Seifim: During Minchah [we say אשרי and ובא לציון and ואני תפלתי, etc] (Tur) we take out one Torah and read three aliyot totaling 10 verses from the next week's parshah. And even when Yom Tov falls on Shabbat we read the next week's parshah and not the one for Yom Tov.

2. We say צדקתך. And if (Shabbat) falls at a time where, if it were a weekday, we would not say Tachanun at Minchah time, we do not say צדקתך. RAMA: And our custom is not to establish a study session between the Afternoon Service and the Evening Service (Tur; Zohar Terumah 279), but we say Pirkei Avot in the Summer, and שיר המעלות in the winter, each place according to its own custom.
