Assalamualaykum sheikh, I ask Allah to bless you. Is it permissible to take knowledge from non Muslims in worldly matters by watching their videos / reading their books? Some of their stuff is beneficial but non Muslims tend to swear a lot and I don’t like exposing myself to that type of language.

Ustadh AbdulAziz al-Haqqan

If they swear alot don't watch th, watch and read for someone else who doesnt do that, and yes it is allowed without cussing or involving that which is forbidden
