assalamualaikum
my sister who lived for five years iun canada now calls herself a salafi.she says that she dont follow any fiqh or imam but the way of Muhammed peace be upon him and sahaba may Allah be pleased with them all.she prays her exactly like men pray and she says bad about our deobandi ulema.she is very hard to convince and she criticizes the four imaams.
i dont know about the salafi aqueeda and dont want to argue with her but i feel pain for her.she dont believe in tasawuf and she makes fun of it.
i want to help her in finding the right way she has been removed and want to convince her but without knowing the truth about salafism its not quite possible.
could my brothers and sisters enlighten me on this subject.
jazaka Allah khair
