Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once mentioned:

I wish to explain a very important principle which I constantly advise my friends. I have heard this important principle from my elders. This principle is also recorded in the malfoozaat (sayings) of my respected uncle Hazrat Moulana Ilyaas (rahmatullahi ‘alaih) and further explained and expounded upon by his son Moulana Yusuf (rahmatullahi ‘alaih) in his discourses. In reality this principle is extracted from the hadeeth.

A person should not be more concerned about how others deal with him and fulfil his rights. Rather, he should be more concerned about how he deals with others. He should constantly ensure that he fulfils the rights of kinship towards his family, the rights of people in general when interacting in society, and he fulfils the laws of sharee‘ah placed upon him in regard to the Creation. (Suhbate baa Awliyaa pg. 93)
