Do I have to keep searching for every wrong online statement I ever made?
See title. If a person has repented, multiple times, but still has statements of kufr online from long ago which he didn’t take offline yet, is he a disbeliever in Islam?
Wa’alaykum as Salam wa rahmatullahi wa barakatuhu,
Whilst a person will not become a disbeliever because of his blasphemous statements which he wrote whilst still not a Muslim, it will be better to remove those statements.
A brief search via google and on forums which you wrote will be sufficient. If you can delete those posts, then you should delete them. Otherwise, atleast write a retraction.
