A: Haamidaw wa Musalliyaa
Gelatin acquired from Halal animals that have been slaughtered in the Halal manner is indeed Halal. As for the gelatin derived from Halal animals that have not been slaughtered according to Islamic rites, there is a difference of opinion among Ulama with regards to whether it is Halal or not.
In view of this difference, it is best to abstain from such gelatin.
And Allah Ta'ala Knows Best
