Assalaamu alaykum bhai jaan, missing you very much. The answer to your question is in the citation. Find out where did Hazratwala db say this and what was the context, who was he speaking to? If this is general advice to all people, including his son, then thats all it is a general advice. Like his son, you dont have to accept it if you dont want to. He was not issuing a command I dont think, he was just giving general advice.
