Dialouge confusion!!

Hey guys, I know that this is far too late, but wanted to discuss this topic since when. wanted to ask about the superhit dialogue of KMH Is it.. Ek "din" ke liye duniya de di.. buss itni mohabbat hai OR Ek dil ke liye duniya de di.. buss itni mohabbat hai !! (Actually culd not make out due to Aorhi's stuffy nosy dialogue.. ha ha ha!!)

It is Ek Dil Not Din Yaar !

Hehe !
