I have heard that the only posuk in ashrei which requires repetition if one did not have kavanah when saying it is פותח את ידךָ. Where is the source for that?
1 Answer
The source is Rabbeinu Yona Brachos 32a, in the name of the Geoinim.
This is brought in Shulchan Aruch Orach Chaim 51:7
The Mishna Brurah there (:16) says it means to say from that posuk until the end of the chapter. Shulchan Aruch HaRav (51:8) implies that saying the single verse is enough.
Kitzur Shulchan Aruch (14:2) implies that the single verse is all that is required as well.
