salam- mubtada' marfoo3 wa 3alamat raf3ihi al damma
qawlan- (no idea)
min- harf jar mabni 3ala al sokoon
rab- ism majroor wa 3alamt jarihi al kasra
rahim- (i think it's a sifa but i'm not sure)

Please someone correct me if I'm wrong, arabic is not my stronger language...

 

[Faye]

Why is the mubtada nakirah?
Is Qawlan maybe some form of Mafool alMatlaq? If so of what fael?
Where is the Khabar?
What is the Shibh ulJumlah 'min rabin arRahim' mutalliq to?

 

[crayon]

The shibh aljumla is fi mahal rafi3 khabar al mubtada i think..
As for the rest I don't know..
