הלכה על ברכות 8:19

Pesukei De-zimra is recited in a relaxed manner and not hastily (SA 51:8). One must especially have kavana when reciting Tehilla Le-David (Ashrei, Tehilim 145). The Sages teach that one who recites this psalm every day earns life in the next world (see Peninei Halakha: Prayer, ch. 14 n. 5) because its praises are arranged according to the order of the Alef Bet and it contains the important verse, “Pote’aḥ et yadekha…” (“You open Your hand and satisfy the desire of every living thing”) (Berakhot 4b). One who realizes that she did not pay attention while reciting that verse must repeat it with kavana, even if she already started reciting other passages (SA 52:7; Peninei Halakha: Prayer, 14:3 n. 5).
