I am looking for any sources (preferably Ashkenaz) on how to say Hamapil/Shma Al Hamita. What I mean is: in many siddurim/cards I see the Bracha first and Shema right after. I’ve also heard to say the Bracha last is the best approach. I am specifically looking for sources on these two questions:
- Where does the Bracha go: before or after Shema?
- Where does Tehillim 91 go? At the end or before the Bracha?
