it’s simple.. if u wanna read about their lives, just type Aga Khan IV or begum Inaara on google.. because unfortunately i don’t know of any website rite now.. and plz go to some decent website, not the ones that bash every sect and give fatwas of declaring others out of ''islam"…
that might hav been a liberal ismaili.. according to strict ismailis (like my mother), animals that are halal to us have to be slaughtered in an islamic way for them to be halal… chickens killed in an unislamic way are not halal coz they’re not slaughtered the right way.. but i personally eat chicken or beef after saying Bismillah… as far as salah (or dua as we call it) cannot be if you are capable of performing it.. our present imam (A.S) has a farman in which he says “nothing makes me more happy than my jamat coming to jamat khana regularly (for saying dua/salah)”
for us, imam mehdi is the imam of any present time.. regarding hazrat isa (A.S), if it’s in the quran or authentic hadith of Huzoor (S.A.W) or sayings of any imam(A.S), then we are obliged to believe in it..
