What is "Sha'anan mi'Pachad Ra'ah"?
1.
Rashi: He is serene in the world to come, and will not fear Gehinom. Sha'anan is future, therefore it has a Patach under the Nun.

Malbim: He is serene from evil fear. Chachmah will guard him from every external fear - no bad mishap will befall him (like Tehilim 91:10).
